1. Describe the functional anatomy of the spinal cord using the following terms: white matter, gray matter, tracts, roots, and spinal nerves. 2. Define the terms reflex and spinal reflex, and identify the components of a reflex arc.
3. Define the term spinal cord injury (sci) and state its prevalence.
4. Define the terms neurological level, tetraplegia, and paraplegia.
5. Define the terms dermatome and myotome and explain how each relates to sci.
6. Define the term stretch reflex and describe how such reflexes are used to anatomically localize sci.
7. Based upon the results of Jason's neurological exam, what is the neurological level of his sci?
8. Discuss the management of sci and the factors that determined the prognosis for this condition.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !
