Anatomy Origin: Posterior tubercles of the transverse processes of C4 to C7. Insertion: Upper surface of the 2nd rib, posterior to the attachment of serratus anterior. Key Relations: Smallest and deepest of the scalenes. Functions -Elevates the 2nd rib. -Lateral flexes the neck to the same side. -An accessory muscle of inspiration. Supply Nerve Supply:

Anatomy Attaches from the lateral tubercle of the talus to the upper and medial aspect of the calcaneus. Functions Provides static stability to the talocalcaneonavicular. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Course A branch of the popliteal artery. It originates after the popliteal artery exits the popliteal fossa. It passes under the tendinous arch formed by the soleus muscle and descends in the plane between the solus and the tibialis posterior muscle. It enters the foot by passing behind the medial malleolus, through the tarsal

Anatomy Course Begins at the junction of the lateral and medial plantar veins. It ascends to the leg, passing behind the medial malleolus and travels deep in the posterior aspect of the leg. It passes under the tendinous arch formed by the soleus muscle and becomes the popliteal vein in the popliteal fossa. Drain Drains

Anatomy Attaches from the posteriolateral surface of the distal tibia to the posterior medial surface of the lateral malleolus. Functions Firmly links the distal ends of the tibia and fibula. This is essential to produce the framework for the articulation of the ankle with the leg. Interested in taking our award-winning Pocket Anatomy app for

Anatomy Course Formed when the splenic and superior mesenteric veins merge behind the pancreas. It ascends to the liver, passing posterior to the superior duodenum. It divides into right and left branches as it enters the liver. Drain Brings blood for detoxification from the gastrointestinal system to the liver, where it rejoins the systemic circulation.

Anatomy A gyrus located posterior to the central sulcus. It extends anteroinferiorly from the great longitudinal fissure and ends just above the lateral sulcus. It forms part of the parietal lobe. Blood supply: Supplied by the middle cerebral artery, and medially by the anterior cerebral artery, to a lesser extent. Functions Is the location of

Anatomy Course A branch of the external carotid artery. It branches from the external carotid just above the posterior belly of the digastric muscle. It then ascends posteriorly behind the parotid gland, near the cartilage of the ear. Supply Supplies the auricle of the ear, as well as some of the scalp behind it. Interested

Anatomy Course Begins from a plexus on the side of the scalp. It descends behind the ear to join with the posterior facial vein. These both form the external jugular vein. Drain Drains the blood from the region of the scalp behind the ear. Interested in taking our award-winning Pocket Anatomy app for a test

Anatomy Two layered membrane in thorax, folded on itself like a deflated but tied balloon, ie there is a potential cavity (if it were re-inflated). Between the pleural layers is a small amount of lubricant fluid that allows touching sides to slide over each other. One side (parietal – sensitive to pain) is externally attached
