The ribs surround the organs of the thoracic cavity. • The lower part of the ventral cavity is divided into two parts‚ abdominal and pelvic portions. • The abdominal cavity contains most of the gastrointestinal tract‚ kidneys‚ and adrenal glands

Action Potentials in the Ventral Nerve Cord of the Periplaneta Americana Andrew Goldsmith (andrew.goldsmith@uconn.edu)‚ Tuesdays 1-4PM Section: 2 (Partner: Ana Charalambides) Abstract In polikiotherms it is known that the amount of locomotion varies based on the environmental temperature. We believe that this is caused by differences in the neural activity. We therefore investigated how temperature changes affect the extracellular neural activity in the ventral nerve cord of the Periplaneta Americana

including muscular dystrophy‚ inflammation of muscles‚ pinched nerves‚ peripheral nerve damage (damage to nerves in the arms and legs)‚ amyotrophic lateral sclerosis (ALS)‚ myasthenia gravis‚ disc herniation‚ and others. Why is an EMG test done? An EMG is often performed when patients have unexplained muscle weakness. The EMG helps to distinguish between muscle conditions in which the problem begins in the muscle and muscle weakness due to nerve disorders. The EMG can also be used to detect true weakness

on to the olfactory nerve. This nerve enters the brain and will cause the subject to understand the odor to be hamburger‚ of which he wants to eat. The brain then makes the decision to move forward with eating the hamburger. The brain must tell the hand to reach out and grab the burger to bring it to the mouth. It does so by sending an impulse down the spinal nerve until it branches off on to the arm nerves‚ which include the radial‚ ulnar‚ and median nerve. These three nerves in conjunction will

It is made up of the Central Nervous System (or CNS) and a network of nerves that extend from the CNS to all parts of the body. The nervous system regulates both voluntary activities‚ such as walking and talking‚ and involuntary activities‚ such as breathing‚ which you make no conscious decisions about. The CNS has two main

Cells combine to form four primary tissues: - Epithelial tissue - Connective tissue - Muscle tissue - Nerve tissue BACKGROUND:A tissue is a group of cells that have a similar shape and function. Different types of tissues can be found in different organs. In humans‚ there are four basic types of tissue: epithelial‚ connective‚ muscular‚ and nervous
