ZOO 3733C Lecture Notes - Lecture 8: Long Thoracic Nerve, Aortic Valve, Phrenic Nerve
Document Summary
Bicuspid valve is also known as mitral. Valvular insu ciency or incompetency: if a valve does not close and produces back. Aortic valve opens and 70 ml of blood is ejected into the aorta. Then, the iv pressure decreases and aortic valve closes: diastole: isovolumetric relaxation. Av valve opens and 70 ml of aloof goes to the ventricle passively and at the end of this period, there is atrial systole. Know which branches of the coronary arteries are giving the blood supply to where. Breast extends vertically from 2nd to 6th rib: 2/3 rests on pectoralis major, 1/3 rests over serratus anterior, areola enlarges during puberty. It contains sebaceous glands: innervation: 2-6 intercostal nerves (t2-t6 dermatomes) Phrenic nerve innervates the diaphragm and pletonium over the liver and gallbladder. Mastectomy: long thoracic nerve might be in danger. Klinefelter syndrome (xxy) is the most common congenital cause of infertility in.
