Academic Success Center. Their enzymes act at an acidic pH. Chapter 3 PowerPoint. It is a prominent, deeply stained spherical inclusion about one-third the size of the nucleus. They are present throughout the central nervous system, but tend to be inconspicuous in mature normal tissue and are difficult to identify with the light or electron microscope. They are composed of three subunits that are arranged to form a 10-nm diameter tubule. Many of these cell inclusions are responsible for the expression of genetic information controlling the synthesis of cellular proteins involved in energy production, growth, and replacement of materials lost by attrition. As these cells become specialized, they lose their ability to differentiate into all tissues. As described in Chapter 6, it also acts as a receptive area for synaptic inputs from other cells. 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. Chapter 5 - Energy - Whole Package - Copy (1) (2). Chapter 20 - The Cardiovascular System: Blood Vessels and Circulation. These tiny fluid-filled sacs house components responsible for the thousands of biochemical reactions necessary for an organism to grow and survive. An epithelial membrane is composed of an epithelial layer attached to a layer of connective tissue. 9) or for the person who first described them (e. g., Purkinje cells shown in Figure 8.

Each germ layer is identified by its relative position: ectoderm (ecto- = "outer"), mesoderm (meso- = "middle"), and endoderm (endo- = "inner"). The dense material on the postsynaptic side is a site where receptor proteins and channels are prevalent. 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). 5 Initial Segment and Axon Hillock. Chapter 3 cells and tissues answer key.com. For example, the amino acid glutamate is taken up by astrocytes and inactivated by conversion to glutamine. Protoplasmic astrocytes are found primarily in gray matter. View the shape of a Purkinje cell stained to show its features. Many of the terms used in this section are defined below. They are the predominant cell type in white matter where they are often located as rows of cells between groups of neuronal processes. Embryonic Origin of Tissues. This preview shows page 1 - 5 out of 15 pages.
Nervous tissue allows the body to receive signals and transmit information as electric impulses from one region of the body to another. Postsynaptic density is darkly staining material of postsynaptic cell adjacent to the synapse. Microfilaments within the axon are usually associated with an area adjacent to the plasmalemma and often are the most dense at the nodes of Ranvier.
Mitochondria are distributed ubiquitously throughout the cytoplasm of the entire nerve cell and are especially plentiful at presynaptic specializations. This is the choroid plexus studied in the Laboratory that is responsible for the secretion, uptake and transport of substances to and from the CSF. Golgi apparatus is a collection of stacked, smooth-surfaced membrane bound organelles where proteins and lipids made in the endoplasmic reticulum are modified and sorted. Chapter 3 cells and tissues answer key anatomy and physiology. In inhibitory neurons the synaptic vesicle are often flattened as shown in Figure 8.
Chapter 3 Cells And Tissues Answer Key Anatomy And Physiology
There is a distinct synaptic cleft or intercellular space of approximately 20-40 nm. Pancreatic Cells' Enzyme Products. They are made up of dimers of α and β tubulin subunits and contain associated proteins known as microtubule associated proteins (MAPS). Chapter 3 cells and tissues answer key page 45. For instance, an average spinal motor neuron with a moderate-sized dendritic tree, receives 10, 000 contacts, with 2, 000 of these on the soma and 8, 000 on the dendrites. Anatomy & Physiology 2.
The synaptic cleft is the gap between the membrane of the pre- and postsynaptic cell. 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). Membrane Transport Transcript. As shown in Figure 8. Identify the four types of tissue in the body, and describe the major functions of each tissue. Student/Faculty Email. A predominant MAP in axons is tau. After reviewing the Model Neuron above, learn more about the function of each structure by tapping from the list below. Furthermore, there are hundreds of different types of neurons based on morphology alone. PDF transcript of the chapter three recorded lecture. Epithelial tissue is made of layers of cells that cover the surfaces of the body that come into contact with the exterior world, line internal cavities, and form glands. Chapter 17 - The Endocrine System. Click the identified structures on the model neuron to move to the related section.
They contain some enzymes that either produce or degrade hydrogen peroxide. Neuroglia are classified based on size and shape fo their nucleus and distinguished from neurons, at the light microscopic level. These different types of synapse are designated by combining the name of the structure of the presynaptic element with that of the postsynaptic structure. Mucus, produced by uniglandular cells and glandular tissue, coats the epithelial layer. Link to a gif showing dispersion/diffusion. Check Financial Status. This area is free of ribosomes and most other cell organelles, with the exception of cytoskeletal elements and organelles that are being transported down the axon. Connective tissue, as its name implies, binds the cells and organs of the body together. This dense material on the presynaptic side is thought to be the site of vesicle attachment. 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 processes of oligodendrocytes are fewer and more delicate than astrocytes, and the cell body shape is polygonal to spherical. Graduation/Transcripts. In some cells, masses of deeply staining chromatin are visible in the nucleus.

The general appearance of microglia is similar to oligodendrocytes, although they are smaller and have undulating processes with spine-like projections. The dendritic processes may branch extensively and are often covered with projections known as dendritic spines. 8 Cellular Elements at the Typical Nerve Terminal. Chapter 13 - Anatomy of the Nervous System. How do somatic stem cells differ from embryonic stem cells? These probably mediate ion exchange between cells. C. Fibrous astrocytes.
Neurofilaments are involved in the maintenance of the neuron's shape and mechanical strength. More recently, cells have been named for their function or the neurotransmitter they contain (e. g., CNS norepinephrine cell groups covered in Chapter 12). After fertilization, the zygote gives rise many cells to form the embryo. Connective Tissue Membranes. This type of membrane may be found encapsulating an organ, such as the kidney, or lining the cavity of a freely movable joint (e. g., shoulder). Chapter 21 - The Lymphatic and Immune System. It has been estimated that there are roughly 360 billion glial cells, which comprise 80-90% of the cells in the CNS. The classical view of the dendrite is that of an unmyelinated tube of cytoplasm which carries information toward the cell body. At the distal-most end of the axon and its collaterales are small branches whose tips are button-shaped cytoplasmic enlargements called terminal boutons or nerve endings. On the left is the pyramidal cell named for its characteristic pyramid shape. Also, the oligodendrocyte forming a particular myelin internode (i. the myelin between two nodes) is seldom seen directly adjacent to the myelin-wrapped process.
More recent evidence indicates that the astrocytes can dramatically change size as part of their physiological regulation of the neuronal environment. Moreover, more than one oligodendrocyte contributes to the myelination of a single internode of an axon. C. Protoplasmic astrocytes This answer is CORRECT! The zygote divides into many cells.
A tissue membrane is a thin layer or sheet of cells that either covers the outside of the body (e. g., skin), lines an internal body cavity (e. g., peritoneal cavity), lines a vessel (e. g., blood vessel), or lines a movable joint cavity (e. g., synovial joint). Course Hero uses AI to attempt to automatically extract content from documents to surface to you and others so you can study better, e. g., in search results, to enrich docs, and more. As in other cells, the principal component of the nucleus is deoxyribonucleic acid (DNA), the substance of the chromosomes and genes. These fine sheet-like processes give the protoplasmic astrocyte cell body a "fuzzy" or murky appearance under the light microscope.
