Muscular and Reproductive System

By : Nash Tannehill

Muscular System

The Muscular System is responsible for maintaining posture and and movement of the body. Skeletal Muscles contract by binding actin and myosin with the sarcomas creating cross-bridges and slide past one another, creating a contraction.

Diseases in the Muscles

Inflammatory Myopthies is a progressive weakening of the skeletal muscles. Symptoms are fatigue after walking and standing, there aren't really any cures but they can give you medication to temporarily take away the symptoms.


Dermatomyositis is just weakness in the muscles and symptoms include rashes swelling and weight loss. skin of muscle biopsy may be necessary.

Reproductive System

The purpose of the reproductive system is to reproduce sexually. Spermatogenesis is the process in which spermatozoa are produced from male primordial germ cells. Oogenesis is the creation of an ovum, the reason why the ovums are unequal is because when the LH surge occurs it sort of gives one ovum the advantage.

Diseases in the Reproductive System

Endometriosis : a condition involving colonization of the abdominal/pelvic cavity with islands of endometrial tissue, symptoms include abdominal pain and nausea. Treatments are multiple hormones.


Varicocele : dilated and twisted veins of the testis. Symptoms are the swelling one one side of the scrotum and discomfort, treatments include microsurgery and sclerotherapy.
