Due to its inferolateral orientation in the thorax, the right atrium and ventricle face anteriorly, while the left atrium and ventricle face posteriorly. We will start with a cross section of the head, where the different structures of the brain are visible. From anterior to posterior, they are named fibularis longus and fibularis brevis. The frontal bone articulates with the greater wing of the sphenoid posteriorly, which in turn articulates with the parietal bones. A new aponeurotic structure appears in the deep posterior compartment. 3 The intermediate dorsal cutaneous nerve courses along the tibiofibular syndesmosis, passes over the root of the inferior extensor retinaculum, crosses obliquely the fifth and fourth extensor digitorum longus tendons, and courses over the third intermetatarsal space. The basal ganglia (head of caudate nucleus, globus pallidus, putamen) are located anterior to the thalamus and they are separated from the thalamus by the posterior limb of the internal capsule. Finally, let's clarify the neurovasculature of the thigh. The tendon is connected, like the corresponding tendons of the fingers, by vincula tendinum, to the phalanges of the toes. Pelvic and lower extremity physiological cross-sectional areas: an MRI study of the living young and comparison to published research literature. The lateral and intermediate roots envelop the origin of the extensor digitorum brevis, unite, and form the stem of the inferior extensor retinaculum. Leg: Cross Sections and Fascial Compartments.
The buccinator muscle follows the contour of the tongue. The tunnel of the flexor hallucis longus is located between the adductor hallucis and the flexor hallucis brevis lateral head. J Foot Ankle Res 14, 5 (2021). Looking at transverse anatomical sections is similar to looking in the mirror, so keep this trick in mind when examining any axial image. Competing interests. Cross sectional anatomy. The medial compartment lodging the abductor hallucis muscle is under the first cuneiform. The tunnel of the flexor hallucis is most superficial.
Lube J, Cotofana S, Bechmann I, Milani TL, Özkurtul O, Sakai T, Steinke H, Hammer N (2015) Reference data on muscle volumes of healthy human pelvis and lower extremity muscles: an in vivo magnetic resonance imaging feasibility study. The flexor hallucis longus is lodged in a tunnel delineated by the adductor hallucis and the flexor hallucis brevis. Campbell EL, Seynnes OR, Bottinelli R, McPhee JS, Atherton PJ, Jones DA, Butler-Browne G, Narici MV (2013) Skeletal muscle adaptations to physical inactivity and subsequent retraining in young men. In this case, they face the trunk due to pronation. Here it crosses the tendon of flexor hallucis longus, from which it receives a tendinous slip. The abdominal aorta has a different shape due to the branching off of the superior mesenteric artery. In 25% of the cases the inferior extensor retinaculum has an oblique superolateral extension band that gives to the retinaculum a cruciate configuration. Materials and methods. Along the tibial aspect of the leg and across the anterior aspect of the ankle and the dorsum of the big toe, the lines run parallel to the long axis of the foot. Each niche is formed by the base of the proximal phalanx, the attached capsuloligamentous cuff, and the plantar plate. Cross section of lower leg avenue. The posterior peroneal artery is located in the tunnel of the flexor hallucis longus. Clin Orthop Relat Res 467:1074–1082.
The next section that we are going to explore is a section of the forearm. The tibialis posterior tendon is medial to the flexor digitorum longus tendon: the crossing of the two tendons has occurred and this level is considered the beginning of the tibiotalocalcaneal tunnel. A different view of section X is provided in Figure 9. The vastus medialis and vastus intermedius are located deep within the anterior compartment, close to the femur. Cross-Sectional and Topographic Anatomy. Section I is an oblique section passing through the posterior talocalcaneal joint. Assessment of quadriceps muscle cross-sectional area by ultrasound extended-field-of-view imaging. The talar head is located medially at the midpoint of a line joining the tuberosity of the navicular to the tip of the medial malleolus.
J Rheumatol 37:282–284. 7%) across days [23]. Understanding the anatomy of the thorax can be challenging. 6 ed: Lippincott Williams & Wilkins; 2012. The sagittal septa of the.
