The repeatability across operators and measures deserves further refining and research. Leg: Cross Sections and Fascial Compartments. J Appl Biomech 23:20–41. Both are innervated by the superficial fibular nerve. Cross-Sectional and Topographic Anatomy. On the medial border of the foot the tuberosity of the navicular is palpated and, farther distally, the tubercle of the first metatarsal base; the latter is located at the midpoint of the medial border of the foot. The trachea is no longer visible because it has split up more superiorly to the main bronchi. Each participant was imaged with both US and MRI one time. The interossei tendons are seen in their insertional positions on each side of the corresponding lesser metatarsal head.

Surg Radiol Anat 39, 849–857 (2017). Leg muscle cross-sectional area measured by ultrasound is highly correlated with MRI | Journal of Foot and Ankle Research | Full Text. Leg muscle cross-sectional area measured by ultrasound is highly correlated with MRI. Sheehan FT (2012) The 3D in vivo Achilles' tendon moment arm, quantified during active muscle control and compared across sexes. The sural nerve, after turning around the lateral malleolus, divides into two branches—lateral and medial—at the base of the fifth metatarsal bone. Understanding the anatomy of the thorax can be challenging. The incomplete pelvic girdle in this cross section surrounds three central visceral structures.
Generally speaking, it is very easy to recognize a cross section through the leg, mostly due to the tibia. Plantar aponeurosis projecting into the central intermediary compartment are already seen. Let's now move on to the lower extremity and look at a couple of cross sections. 1007/s10439-007-9334-6. Cine loops were recorded of the contraction cycle to help visualize the fascial borders of the muscles and the conformational changes within the muscle. Cross sectional anatomy. From these measurements, the 30 and 50% distances from the knee joint line were determined and marked with a soft-tipped marker. Noorkoiv M, Nosaka K, Blazevich A. 449 cm2 for the tibialis anterior muscle at 50%. Crofts G, Angin S, Mickle KJ, Hill S, Nester C. Reliability of ultrasound for measurement of selected foot structures. The PCSA of the pelvis, thigh, and leg muscles tended to be 20–130% larger in males than in females, except for the gemelli which were 34% smaller in males, and semitendinosus and triceps surae which did not differ (<20% different).

Bloem B, Allum J, Carpenter M, Honegger F. Is lower leg proprioception essential for triggering human automatic postural responses?
Cross Section Of The Leg
Over the lateral and the medial borders of the foot, the lines are longitudinally oriented. The primary purpose of this study was to establish the validity of leg muscle CSA measurements acquired from US images. A thick band of deep fascia that stabilizes the hip (iliotibial tract) descends along the lateral aspect of the thigh between the vastus lateralis and biceps femoris muscles. Each participant read and signed an informed consent approved by the University's Institutional Review Board (study protocol, IRB2019–375). L4||Iliac crest, bifurcation of abdominal aorta|. Cross section of the lower leg. At the level of the sinus tarsi, a second soft tissue bulge is frequently found, representing the well-developed origin of the extensor digitorum brevis muscle. Ronald A. Bergman, Ph. The inferomedial arm of the retinaculum courses anteromedially and reaches the medial border of the foot at the level of the cuneonavicular joint.
The lateral compartment is limited to the undersurface of the fifth metatarsal. 29 is a close-up view of the coronal section through the metatarsal head of the big toe (distal surface of section). You know that the thorax contains a major organ called the heart. Journal of Foot and Ankle Research volume 14, Article number: 5 (2021). The brain has been replaced instead by a vertebra with an atypical structure (axis), the spinal cord and several muscular layers of the neck. Cross section of the leg. The next section that we are going to explore is a section of the forearm.
Four cerebral lobes are visible, from anterior to posterior: frontal, insular, temporal and occipital lobes. The use of real-time ultrasound imaging for biofeedback of lumbar multifidus muscle contraction in healthy subjects. Our first stop is the thigh. The posterior compartment of the leg is the largest and most complicated of them all. The medial root originates in the sinus tarsi, next to the intermediate root; in the canalis tarsi it is anterior to the interosseous ligament and sends an arm to the talar roof of the tarsal canal. The head is an anatomical structure that rests on top of the mobile neck. Eichenseer PH, Sybert DR, Cotton JR (2011) A finite element analysis of sacroiliac joint ligaments in response to different loading conditions. The second specimen provided coronal sections of the hindfoot and tarsus. Regardless of imaging modality used, it is important to calculate measures such as the MDD when tracking muscle size changes over time. These data suggest that either imaging modality can be used to track changes over time. It contains a variable amount of adipose tissue. It's now time to move on to the trunk, where the thoracic and abdominal organs are located. Shahan K. Sarrafian. Tibialis anterior forms the bulk of the anterior compartment.
Cross Section Of The Lower Leg
The sesamoid articular surfaces are oriented obliquely and articulate with the corresponding concave metatarsal articular surfaces separated by a crest. While less operator dependent, MRI is still highly sensitive to participant positioning [24]. At first sight, the delineation of the borders of this retinaculum might not be very clear, because distally it is in continuity with the dorsal aponeurosis and proximally with the distal segment of the aponeurosis cruris and the superior extensor retinaculum. However, there are quite a few differences between them. The tendon is connected, like the corresponding tendons of the fingers, by vincula tendinum, to the phalanges of the toes. To prevent confusion, think in terms of radial and ulnar sides because they are more logical and easier to locate. The forearm is pronated in the above cross-section. The posterior compartment contains only the triceps brachii muscle, which is located posterior to the intermuscular septa. These two branches are reinforced by the deep peroneal nerve. Cross-sections are two-dimensional, axial views of gross anatomical structures seen in transverse planes. The splenius capitis is overlaid by the upper part of the sternocleidomastoid muscle, close to its insertion point. The tibialis posterior tendon has inserted on the tuberosity of the navicular. 3 The nerve divides into its terminal branches—intermediate and medial dorsal cutaneous nerves—at an average of 6.
Let's explore a cross-section of the forearm at the level of the flexor carpi ulnaris muscle: Getting your bearings in the above cross-section is not easy because the forearm can have different orientations in space, depending if it is pronated or supinated. The authors have no conflict of interest related to this study. This band originates from the lateral sling, from the superomedial band, or from both. It contains two bones (radius, ulna) and two muscle compartments: anterior (flexor) and posterior (extensor). J Nutr Health Aging 14:362–366. The fibularis brevis was measured at 50% of the shank length with the fibula serving as an anatomical landmark just deep to the fibularis brevis. 2 The venous network is formed centrally by longitudinally and obliquely oriented veins and distally by the dorsal venous arcade, which receives the superficial dorsal metatarsal veins. T6||Upper border of liver|. Several bones of the neurocranium are visible beneath the soft tissues, from anterior to posterior: frontal, sphenoid, parietal and occipital bones. Chang R, Kent-Braun JA, Hamill J. Two muscles of mastication (temporal, lateral pterygoid) are visible posterolateral to the maxillary sinus.
First of all, the brain is no longer visible because this particular transverse cut passes below the base of the skull. The superficial peroneal nerve trunk is usually found subcutaneously along the anterior border of the fibula, 10. The brain (namely the brainstem and the cerebellum) points posteriorly (bottom of the image) and as you know from anatomy, the skull bones containing the paranasal sinuses are located anteriorly (top of the image). Medial to the iliopsoas muscle one can see the external iliac artery and vein. The pelvic girdle forms the framework of the pelvis. Since the ribs of the thoracic cage are oriented inferiorly, portions of the second, third and fourth ribs are visible around the contour of the lungs. Flack NA, Nicholson HD, Woodley SJ (2014) The anatomy of the hip abductor muscles. The leg is the region of the lower extremity that extends between the knee and ankle joints. Take a sneak peak at the resources offered below and start identifying them under exam conditions.
Due to the level of the cross-section, only the pubic bone (anterior) and ischium (posterior) are observed. It also has an irregular internal border (mucosal folds). The abdomen doesn't simply stop at the level of T11. The tibia and fibula are the two bony pillars of the leg, anchoring several muscles. For all measurements, standard error of the measurement ranged from. The lateral compartment lodges the peroneus longus and brevis muscles. The star of the show (brain) is easily recognizable because it appears highly convoluted, full of ridges (gyri) and indentations (sulci).
