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 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?
