When the colon begins to turn medially, it becomes the sigmoid colon. They are two separate endocrine glands, with different embryological origins: The cortex and medulla synthesise different hormones. The subtalar joint is an articulation between two of the tarsal bones in the foot the talus and calcaneus. The subtalar joint is formed between two of the tarsal bones: As is typical for a synovial joint, these surfaces are covered by articular cartilage. These anastomoses form a continuous arterial channel which extends the length of the colon - the marginal artery. A comprehensive etymological dictionary of the English language. The Purkinje fibres (sub-endocardial plexus of conduction cells) are a network of specialised cells. The right gland is pyramidal in shape, contrasting with the semi-lunar shape of the left gland. The marginal artery (of Drummond) is a clinically important vessel thatprovides collateral supply to the colon - thereby maintaining arterialsupply in the case of occlusion or stenosis of one of the major vessels.

A good memory aid for this is BBC - biceps, brachialis, coracobrachialis. Web. An additional ligament - the interosseous talocalcaneal ligament - acts to bind the talus and calcaneus together. The subtalar joint is usually disrupted, causing the joint to becomearthritic. The transverse colon is the least fixed part of the colon, and is variable in position (itcan dip into the pelvis in tall, thin individuals).

The marginal artery (of Drummond) is a clinically important vessel thatprovides collateral supply to the colon thereby maintaining arterialsupply in the case of occlusion or stenosis of one of the major vessels. As the terminal vessels of the superior mesenteric and inferior mesenteric artery approach the colon, they split into many branches, which anastomose with each other. It helps keep the body stable while walking by allowing the foot to roll in and out. The terms proximal and distal are used in structures that are considered to have a beginning and an end (such as the upper limb, lower limb and blood vessels).

The pelviss frame is made up of the bones of the pelvis, which connect the axial skeleton to the femurs, and therefore acts in weight bearing of the upper body. On a CT scan, it becomes much more clear that, as the calcaneus comes up, it kind of hits against the fibula, it nutcrackers this little fragment here and breaks it off. The ankle joint (or talocrural joint) is a synovial joint located in the lower limb.

The transverse colonextends from the right colic flexure to thespleen, where it turns another 90 degrees to point inferiorly. In practice, there is significant overlap between the two types of classifications. The subtalar joint is an articulation between two of the tarsal bones in the foot - the talus and calcaneus. There are 10 intrinsic muscles located in the sole of the foot. The joint is classed structurally as a synovial joint, and functionally as a plane synovial joint.

These vessels originate from two lymphatic plexuses one deep to the capsule, and the other in the medulla. The subtalar joint receives supplyfrom two arteries and two nerves. The rate at which the SA node generates impulses is influenced by the autonomic nervous system: After the electrical impulses spread across the atria, they converge at theatrioventricular node located within the atrioventricular septum, near the opening of the coronary sinus.

Arterial supply comes from the posterior tibial and fibular arteries. It receives digested food from the small intestine, from which it absorbs water and electrolytes to form faeces. (Tarsal is the latin word for ankle.) Fig 1 The large intestine extends from the cecum to the rectum. The ileocolic artery gives rise to colic, anterior cecal and posterior cecal branches all of which supply the ascending colon.
