Central NS
These are collections of neuron cell bodies
What is Gray Matter?
Sensory Receptors that respond to heat or cold
What is a thermoreceptor
Neurons of the hypothalamus that secrete neurohormones rather than neurotransmitters
What are neurosecretory cells?
These are red blood cells that carry oxygen into the blood.
What are erythrocytes?
These are encapsulated masses of lymph tissue found along lymph vessels.
What are Lymph nodes?
This is a crossing over of neurons from left to right side of the CNS
What is Decussation?
Sensory receptors that respond to excess stimulation or pain
what is a Nociceptor
biologically active lipids that produce many effects in the body including effects on smoother muscle contraction, blood clotting and pain
What are prostaglandins?
These are white blood cells that perform various defensive functions in the body
What are Leukocytes?
This is immunity that comes from antibodies in the blood
What is humoral immunity?
These are functions of the body necessary for life on a minute-to-minute basis
What are vital functions?
What are Cutaneous receptors?
This increases the release of growth hormone from the anterior pituitary gland.
What is Growth Hormone Releasing Hormone?
This is the phase of the cardiac cycle in which the ventricles contract
What is the Systolic phase?
This is immunity that comes from the action of T lymphocytes
What is Cell-mediated immunity?
This if formed by the medulla oblongata, the pons and the midbrain
What is the brainstem?
IN order for us to smell a substance these three conditions must be met.
What are it must be volatile, partly water soluble and partly fat soluable.
This increases water retention by the kidneys
Antidiuretic Hormone?
This is the phase in the cardiac cycle in which the ventricles relax
fluid that flows in the lymph vessels
what is Lymph?
This allows the muscles to react more quickly than they would if neural messages had to travel all the way to the brain and back before a response could occur
What is a reflux arc?
This is the organ of hearing
what is the cochlea?
This hormone lowers blood glucose by enabling cells to take in glucose
What is insulin?
These are small veins that do not have three tunics but instead have only an endothelium, a basement membrane, and a few smooth muscle cells.
What are velules?
This organ filters the blood
What is the spleen?
