inborn and connected through the nervous system‚ or they can be learned through practice. Another way to explain a reflexive category would be autonomic reflexes or somatic reflexes. Autonomic reflexes are those which are unaware to us and act on visceral organs of the body‚ whereas somatic reflexes involve skeletal muscle stimulation. Both types of reflexes are put into effect via the nervous system. (1) The Patellar reflex‚ or Knee-Jerk reflex‚ is used to test the nervous tissue in the spinal cord from

Why do we jump when we watch a scary movie? People jump when watching scary movies because the loud noise or flashing picture (the stimulus) passes through out eyes or ears (the receptor) and our endocrine system responds to the surroundings thus sending electrical impulses to the brain causing our muscles (the effectors) to spasm causing us to jump or scream. In addition‚ the blood has a increased amount of hormonal adrenaline and a higher heart rate. Hormones Hormones are a chemical substance

After neurological testing‚ it is determined that she has a compressed spinal nerve on the right side. a. Which spinal nerve (what level) is affected? The level is C5-T1 cervical nerves. The specific spinal nerve would belong to the brachial plexus‚ the ulnar nerve. b. How did you determine/decide it was this level? The ulnar nerve branches off of the medial cord‚ which is

The brain and spinal cord are made up of many cells‚ including neurons and glial cells. Neurons are cells that send and receive electro-chemical signals to and from the brain and nervous system. There are about 100 billion neurons in the brain. There are many more glial cells; they provide support functions for the neurons‚ and are far more numerous than neurons. There are many type of neurons. They vary in size from 4 microns (.004 mm) to 100 microns (.1 mm) in diameter. Their length varies from
