Immunohistochemical colocalization of estrogen receptor-α and GABA in adult female rat hippocampus.

Background: Hippocampus is an important target for estrogen action. It is severely affected in patients of Alzheimer's disease. Much of the current research related to estrogen and brain function is focused in two directions.

Unusual insertion of the coracobrachialis muscle to the brachial fascia associated with high division of brachial artery.

Anatomical variations of the coracobrachialis muscle (CBM) are common. We detected an abnormal form of the CBM of the left arm during human cadaver dissection. The CBM originated from the tip of the coracoid process of the scapula and divided into muscular and musculo-aponeurotic bellies.
