Within the mediastinum‚ bordered laterally by the lungs‚ posterio0rly by the vertebral column‚ anteriorly by the sternum. 2) Distinguish between the visceral pericardium and the parietal pericardium. Visceral is a membrane that covers the surface of the heart. Parietal is a membrane that forms the outter wall of the peritoneal cavity 3) Describe the layers of the heart wall.

The first and foremost of the surprise is the vast reservoir of chemical factories‚ inside the tiny body. Though this creature does not have a vertebral column‚ a proper demarcation of body and head‚ and not even a brain‚ yet this Jellyfish is seen to possess numerous different chemicals‚ some of which are extremely toxic and poisonous too. Next in store for the observer or the scientist is the next

forefeet (awkward gait) due to the enlarged calves. Between the ages 11 and 13 the young man will often develop skeletal deformities. The back muscles become weak‚ and the spine starts to curve. The spine is a column of small bones called vertebrae. There are five sections of the vertebral column. The body’s weight falls on the lumbar vertebrae. This excessive curvature bends toward the front causing the body to lean forward. This condition is known as Lordosis. In addition‚ lateral curvature of

portion of the nervous system‚ the CNS coordinates the body’s interaction with the environment. The CNS is contained within the dorsal cavity‚ with the brain in the cranial subcavity (the skull)‚ and the spinal cord in the spinal cavity (within the vertebral column). Then human nervous system is the most complex object know to science‚ as it includes the intricate CNS and a brain with 10 billion neurons and many times more interneural connections (Anissimov 2007). For some people‚ this brain and the increase

Scoliosis Gina Amato and Amber Kral Triton College Abstract This research paper is based on the skeletal pathological condition known as scoliosis. Scoliosis is an abnormal lateral bending and twisting of the vertebral column. The following paper presents research on causes along with possible complications that can arise while acquiring this condition. Additional research on tests/exams available to help diagnose scoliosis and how it appears radiographically is also

INTROduction TO THE HUMAN BODY 1. Define anatomy and physiology While anatomy provides us with a static image of the body architecture‚ physiology reveals the body’s dynamic and animated workings. Physiology often focuses on events at the cellular or molecular level. A. Anatomy – studies the structure of the body parts and their relationship to one another. i. Developmental – concerns structural changes that in the body occur throughout the lifespan. Embryology studies the developmental changes
