Functions Secretes alkaline fluid which constitutes ~30% of semen (with spermatozoa and seminal vesicle fluid) and protects sperm against acidic vaginal environment. This fluid is produced constantly, with the excess being expelled in urine. Contains smooth muscles which help project sperm during ejaculation. These muscles also help in involuntary control of urine. Anatomy Complex exocrine

Anatomy A gyrus located anterior to the central sulcus. It extends anteroinferiorly from the great longitudinal fissure and ends just above the lateral sulcus. It forms part of the frontal 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 ileocolic artery that branches off near the junction of the ileum and the cecum. It can branch off together with the anterior cecal artery as a trunk, or individually. Supply The posterior cecal artery supplies the cecum and the appendix. Interested in taking our award-winning Pocket Anatomy app for

Anatomy Course Arises from the sacral plexus in the pelvis. It exits the pelvic cavity through the greater sciatic foramen inferior to the piriformis muscle. It passes to the back of the leg and travels distally beneath the gluteus maximus, and then passes over the long head of the biceps femoris muscle, remaining deep to

Anatomy Course Originates from the common interosseous artery, which is a branch of the ulnar artery. It branches from the common interosseous artery just above the margin of the interosseous membrane, running dorsally. It then runs distally on the posterior aspect of the forearm, until it reaches the wrist joint where it joins with the

Anatomy Attaches from the head of the fibula, and passes obliquely upwards to attach to the lateral condyle of the tibia. Functions Provides static stability to the proximal tibiofibular joint. Interested in taking our award-winning Pocket Anatomy app for a test drive?
