Microfilaments are especially prominent in synaptic terminals, in dendritic spines, and in association with the axolemma. Connective tissue binds the cells and organs of the body together and performs many functions, especially in the protection, support, and integration of the body. The myelin sheath acts to insulate the plasmalemma of the axon in a way that necessitates the more rapid spread of the depolarization of the plasmalemma and increases the speed of conduction of the nerve impulse (see Chapter 3). When lining a joint, this membrane is referred to as a synovial membrane. Microfilaments are 7 nm in diameter filaments arranged as a paired helix of two strands of globular actin. HEALTH SCIENCESPLTW211 - Chapter 2(Azares).docx - CELLS AND TISSUES 3 The basic unit of structure and function in the human body is the cell. Each of a cell’s parts, or | Course Hero. Find d dx log 4 3 x A 1 3 x ln 4 B 1 x ln 4 C 1 x D 3 x ln 4 E 3 x Page 1 of 11. This cell is prominent in the cerebral cortex. Recent studies have indicated that the cleft is not an empty space per se, but is filled with carbohydrate-containing material. They are arranged in a single-layered columnar epithelium, and have many of the histological characteristics of simple epithelium, which vary from squamous to cuboidal depending upon their location.

Ribosomes are particles composed of ribosomal RNA and ribosomal protein which associate with mRNA and catalyze the synthesis of proteins. Upload your study docs or become a. Neuroglia are divided into two major categories based on size, the macroglia and the microglia. Transcript of the membrane transport recorded lecture. Unipolar cells have only one cell process, and are primarily found in invertebrates. Chapter 3 cells and tissues answer key of life. The reacting microglia have a swollen form with shortened processes and are difficult to discriminate from phagocytes from the periphery or migrating perivascular cells. Describe this transition, discussing the steps and processes that lead to these specialized cells.
It is the neurofilaments that undergo modification in the Alzheimer's disease to form neurofibrillary tangles. Microtubules are involved in axoplasmic transport (see below). In light microscopic preparations, the appearance of Nissl substance varies in different types of neurons. The lateral borders of the ependymal cells are relatively straight and form junctions with adjacent cells. This preview shows page 1 - 5 out of 15 pages. Chapter 3 cells and tissues packet answers. Check Financial Status. Peroxisomes are small membrane bounded organelles that use molecular oxygen to oxidize organic molecules. Also, every internode of a PNS axon represents a single Schwann cell. Thus, any disruption in the structure of a tissue can lead to injury or disease.
The dendritic spines often contain microfilaments which is the cytoskeletal element responsible for changes in spine shape observed in some examples of synaptic plasticity. Intercellular adherences have also been observed between fibrous astrocytes. In addition to these general functions, astrocytes also act in more specialized ways to facilitate neuron function. Protein synthesis PowerPoint slideshow with close-captioned recorded lecture. Endoplasmic reticulum is a labyrinthine, membrane bounded compartment in the cytoplasm where lipids are synthesized and membrane bound proteins are made. Bundles of fine fibrils may be seen within the cytoplasm. Macrophages appear in the CNS following injury and work together with the CNS glial cells to phagocytize CNS debris. They are involved in converting proteins to amino acids and glycogen to glucose, the basic nutrient of neurons. Plasmalemma of the neuron appears in the electron microscope as a typical bi-layered cellular membrane, approximately 10 nm thick. Cells and tissues pdf. In addition, microtubules are not continuous, and each microtubule is composed of numerous 100 nm units. After reviewing the Model Neuron above, learn more about the function of each structure by tapping from the list below. However, almost all possible combinations of pre- and postsynaptic elements have been found in the central nervous system. Epithelial tissue refers to groups of cells that cover the exterior surfaces of the body, line internal cavities and passageways, and form certain glands.
Chapter 3 Cells And Tissues Packet Answers
Graduation/Transcripts. The rough ER, in laminae with interspersed ribosomes, is visible with the light microscope as Nissl substance. The dendritic processes and spines of neurons are essentially expansions of cytoplasm containing most of the organelles found in the cell body. Morphologically the "dendrite" and the "axon" may, therefore, be indistinguishable. Explain the process by which a cell builds proteins using the DNA code. In the Peripheral Nervous System (PNS), Schwann cells are responsible for the myelin formation. 5 Initial Segment and Axon Hillock. Link to a video where you can learn about the endomembrane system, which includes the rough and smooth ER and the Golgi body as well as lysosomes and vesicles. A number of conventions have evolved to classify and name neurons. One of the oldest, devised by Golgi in the late 1800's, is based on the complexity of the dendritic tree of the neuron.
More recent evidence indicates that the astrocytes can dramatically change size as part of their physiological regulation of the neuronal environment. Muscle tissue contracts forcefully when excited, providing movement. Cell bodies of oligodendroglia are often located near capillaries, but they lack the definite perivascular end feet characteristic of astrocytes. Microglial nuclei are elongated or triangular and stain deeply with alkaline dyes. Following the cells of the ectodermal germ layer, they too become more restricted in what they can form. Axolemma is the plasmalemma of the axon. Often, neurons that look similar have strikingly different properties. The region between the axon hillock and the beginning of the myelin sheath is known as the initial segment. They are made up of dimers of α and β tubulin subunits and contain associated proteins known as microtubule associated proteins (MAPS). Chapter 10 - Muscle Tissue. Multinucleate Muscle Cell.
On the left is the pyramidal cell named for its characteristic pyramid shape. The first embryonic cells generated have the ability to differentiate into any type of cell in the body and, as such, are called omnipotent, meaning each has the capacity to divide, differentiate, and develop into a new organism. Students should be able to describe neurons and glia, their morphological components as seen with the light and electron microscope, and some of the fundamental functional roles these cell types play in the nervous system. Are less electrically excitable than neurons. The cytoplasm of oligodendrocytes tends to be darker than that of astrocytes with silver stains, and does not contain glial fibrils (although they do contain microtubules). Two basic types of tissue membranes are recognized based on the primary tissue type composing each: connective tissue membranes and epithelial membranes (Figure 4.
Chapter 3 Cells And Tissues Answer Key Of Life
Each of these lines of embryonic cells forms the distinct germ layers from which all the tissues and organs of the human body eventually form. The primary tissue types work together to contribute to the overall health and maintenance of the human body. Mitochondria are often arranged longitudinally. Both types of astrocytes function to support the neurons in their immediate vicinity. These cells myelinate axons differently than the interfascicular oligodendroglia. Which of the following cell types is responsible for the maintenance of pH of the extracellular space of the CNS?
The general appearance of microglia is similar to oligodendrocytes, although they are smaller and have undulating processes with spine-like projections. As will be described later, they also serve as vesicles for reverse transport from axon terminals to the soma. According to the classical definition of synapse, when a nerve ending synapses on a dendrite or soma of a second neuron it is termed either an axodendritic or an axosomatic synapse, respectively (Chapter 7). By the end of this section, you will be able to: - Identify the four primary tissue types and discuss the structure and function of each. In this chapter, you will learn about the major components and functions of a prototypical, generalized cell and discover some of the different types of cells in the human body. Neurons with long axons have a larger cell body and nucleus. Dendrites contain numerous orderly arrays of microtubules and fewer neurofilaments (see below).
Neither the position of the cell body nor the presence or absence of myelin is always a useful criterion for understanding the orientation of the neuron. The synaptic cleft is the gap between the membrane of the pre- and postsynaptic cell. As in other cells, the principal component of the nucleus is deoxyribonucleic acid (DNA), the substance of the chromosomes and genes. Test Your Knowledge.
Chapter 12 - The Nervous System and Nervous Tissue. Chapter 25 - The Urinary System. Ependymal cells line the ventricles of the brain and the central canal of the spinal cord. These functions will be discussed in later sections. As described in Chapter 6, it also acts as a receptive area for synaptic inputs from other cells. In Nissl stains, the fibrous astrocytes have a nucleus essentially the same as that of the protoplasmic type with a flecked appearance. Link to a video of a tour of a cell. What happens when a terminally differentiated cell reverts to a less differentiated state?
