linea aspera attachments mnemonic

The part of the tendon below the patella, the patellar ligament, is attached to the upper anterior part of the tibia. Abandoning any attempt to homologise between the fore and hindlimbs musculature, we shall merely outline briefly the arrangement of muscles in the rat, and compare with man where possible. On the posterior surface of the tibia, between the condyles, is the popliteal notch. In man, psoas runs from the ventral surfaces of lumbar vertebrae where it is joined by iliacus, running from the inner surface of the ilium, to form a joint tendon that inserts into the lesser trochanter of the femur. Bones; Skeletal system > kep1313. The medial is less marked, especially at its upper part, where it is crossed by the femoral artery. The hamstring portion attaches onto the femur at the adductor tubercle on the inferomedial portion of the bone. To adduction: gluteus medius and minimus, tensor fasciae latae, upper fibers of gluteus maximus. FIGURE 7.23. There are two distal facets, both toward the anterior half of the medial surface. The slender shaft widens distally. Mobile and tablet users, you can download e-Anatomy on Appstore or GooglePlay. The lateral ridge is very rough, and runs almost vertically upward to the base of the greater trochanter. Tim D. White, ... Pieter A. Folkens, in Human Osteology (Third Edition), 2012. The astragalus articulates ventrally with the calcaneum, which lies laterally. The rat has a long hindfoot, so the calcaneus projects well behind the ankle joint, providing good leverage when the digits are pressed to the ground, as in running. The pelvis or hip consists of paired innominate bones (Figure 7.21) that articulate with each other ventrally at the pelvic symphysis and with the sacrum dorsally.

Folkens, in The Human Bone Manual, 2005. This confusing terminology led Dr. Johnson astray when he defined the pastern of a horse as the knee (the pastern is the proximal phalanx). Some fibers merge into the lateral patellar retinaculum, Muscle type: Phasic, prone to weakening under stress, Function: Extends the leg at the knee and draws the patella laterally, Synergists:For knee extension: rectus femoris, vastus medialis and vastus intermedius, Antagonists:To knee extension: biceps femoris, semi-membranosus, semitendinosus, gastrocnemius, popliteus, gracilis and sartorius, Gerardo De Iuliis PhD, Dino Pulerà MScBMC, CMI, in The Dissection of Vertebrates (Second Edition), 2011. On the medial ridged aspect of the linea aspera, the muscle vastus medialis attaches to the femur. In addition, there are the lateral rotators piriformis, obturator externus and internus, quadratus femoris or gemelli; short muscles that run from the pelvis to the upper end of the femur and rotate the femur and stabilise the hip joint. For proximal femoral shafts, the nutrient foramen opens distally, and the linea aspera is posterior and thins inferiorly. No muscles run from within the chest to the forelimb, but a number of muscles run from the ventral surfaces of the lumbar vertebrae to the hindlimb. The lesser trochanter and linea aspera are posterior. Gastrocnemius lies superficial to soleus, and together they combine to produce a single tendon (of Achilles) that is inserted into the calcaneum, from where they plantar-flex (or flex) the ankle. The hamstring part arises from the ischial tuberosity. If available, manipulate the tibia and pes to observe this. It is termed the gluteal tuberosity, and gives attachment to part of the Glutæus maximus: its upper part is often elongated into a roughened crest, on which a more or less well-marked, rounded tubercle, the third trochanter, is occasionally developed. The obturator externus attaches proximally to the obturator foramen margins and membrane and passes to attach distally onto the femur, at the trochanteric fossa. Left tibia and fibula of the cat in (a) anterior and (b) posterior views. By continuing you agree to the use of cookies. Gastrocnemius arises as two heads from the medial and lateral femoral epicondyles and fabellae, and soleus by a slender tendon from the head of the fibula (Greene, 1935). A recent paper by Diogo and Molnar (2014), with the formidable title: ‘Comparative anatomy, evolution and homologies of tetrapod hindlimb muscles, comparison with forelimb muscles, and deconstruction of the forelimb-hindlimb serial homology hypothesis’ is available online, and is worth looking at, if only as an example of the level of scholarship still being applied to the study of comparative anatomy. It is tempting, but incorrect, to assume that are similarities between the muscles of the pelvic and pectoral girdles. The linea aspera is perforated a little below its center by the nutrient canal, which is directed obliquely upward. Left femur and patella of the cat in (a) anterior and (b) posterior views. The lateral malleolus projects distally from the posterolateral end of the fibula. The first is strongly reduced to a small nub that articulates with the medial cuneiform. The phalanges for digit 1 have been lost in the cat. The adductor part attaches distally to the, Leon Chaitow ND DO, Judith DeLany LMT, in, Clinical Application of Neuromuscular Techniques, Volume 2 (Second Edition), : From the inferior ramus of the pubis to the upper third of the medial lip of the, From the anterior and lower surfaces of the greater trochanter, intertrochanteric line of femur, gluteal tuberosity, lateral intermuscular septum and lateral lip of, Gerardo De Iuliis PhD, Dino Pulerà MScBMC, CMI, in, The Dissection of Vertebrates (Second Edition), Anatomy and Histology of the Laboratory Rat in Toxicology and Biomedical Research, Veterinary Clinics of North America: Equine Practice, Flexor digitorum longus and flexor hallucis longus, Flexor digitorum profundus and flexor digiti primi, Plantaris: fusing with flexor digitorum brevis in the sole of the foot, Flexor digistorum superficialis: fusing with flexor digitorum brevis in the sole of the foot. For intact femora or proximal ends, the head is proximal and faces medially.
