The outline is enhanced with an extensive and original illustration program that visually conveys the essential information and promotes retention of the material. Features such as clinical correlations and clinical problems are also included.

the body and tail of the pancreas. FRACTURED RIBS AND THE SPLEEN A fractured 9th, 10th, or 11th rib on the left may lacerate the spleen. The spleen bleeds profusely when lacerated and is usually removed. G. The liver is situated in mainly in the right hypochondriac region and extends into the epigastric region (Figure 4–8). Figure 4–8. The liver. 1. The liver functions as an exocrine gland, producing and secreting bile; bile is released into the biliary duct system. 2. It also functions as
ovarian follicles. OVULATION At ovulation, a secondary oocyte is extruded through the wall of the ovary and into the peritoneal cavity. • The ostium of the infundibulum of the uterine tube is in close proximity to the ovary. • The fimbriae of the infundibulum trap the ovulated ovum and move it to the ostium. FERTILIZATION In fertilization, a sperm fuses with a secondary oocyte; the most common site of fertilization is in the ampulla of the uterine tube. ECTOPIC IMPLANTATION An ectopic
sympathetic axons from paravertebral ganglia course in gray rami, which rejoin all spinal nerve branches to innervate smooth muscle in the walls of blood vessels and sweat glands in the body wall, in both extremities, and in the neck. d. Postganglionic sympathetic axons from paravertebral ganglia also course in cervical and upper thoracic or cardiopulmonary splanchnic nerves to innervate smooth muscle and glands in the lungs, cardiac muscle, and the conduction system of the heart. e.
or a lesion to the cochlear part of CN VIII or to CNS auditory pathways. • Presbycusis is a common cause of high-frequency sensorineural hearing loss in the elderly. It results from a progressive loss of hair cells at the base of the cochlea. • Ménière’s disease is caused by an accumulation of endolymph (endolymphatic hydrops), which results in attacks of tinnitus (ringing) and vertigo. TESTS TO DETERMINE HEARING LOSS TYPE • The Weber test may be used to determine whether a patient has a
might be compressed by an aortic aneurysm. • The right recurrent laryngeal nerve is found only in the neck, where it hooks around the right subclavian artery. IX. The trachea begins inferior to the cricoid cartilage at the level of the C6 vertebra (see Figure 9–10). A. The trachea extends inferiorly into the mediastinum and ends by bifurcating into the left and right primary bronchi at the disk between the T4 and T5 vertebrae. B. The trachea consists of cartilage rings that are incomplete
