The sensory receptors in the integumentary system communicate with the brain and spinal cord via the nerves (the three parts of the nervous system). 6.

Cells of the same type that perform a common function make

When alcohol is consumed the result is un-coordinated movement (Blood Alcohol information 2006-2010). Hypothalamus Majority of the autonomic functions in the brain as well as hormone release is controlled by the hypothalamus. Alcohol acts by depressing the nerve centers in the hypothalamus which control sexual

generally believed that vestibular suppressants act on the neurotransmitters responsible for carrying the vestibular signal from primary vestibular neurons. That is‚ these drugs seek to block the conduction of impulses from the semicircular canals and otolith organs‚ before these nerve impulses reach central vestibular structures (Smith & Darlington‚ 1996). The vestibulo-ocular reflex is a reflex eye movement‚ which is imperative in the control of balance. It functions to stabilize images on the retinas

SA node contracts generating nerve impulses that travels throughout the heart wall. This causes both atria to contract 2. AV node impulse conduction(refractory period) a. Impulses from the SA node reach the AV and are delayed in order to allow the atria to contract and empty) 3. AV bundle impulse conduction a. Impulses are sent

The body–self neuromatrix is a term used to describe the interconnected maze of nerves that carry the painful stimulus to all the different areas of the brain such as the central cortex‚ thalamus and limbic system that are involved in perceiving‚ reacting to and regulating pain. (Keefe‚ Abernethy & Campbell 2005‚ Melzack 2005‚ 2001‚ 1999‚ Moseley 2003) Essentially three different areas of information feed into the neuromatrix. 1.
