    topographical region of the body surface innervated by one nerve root
  39. myotome
    muscle and tissue of the body innervated by a spinal nerve root
  40. 4 Peripheral Nervous System
    • Somatic Sensory- nerves transmit sensations involved in touch, pressure, pain, temp., and position
    • Somatic motor- these efferent fibers carry impulses to the skeletal muscles
    • Visceral sensory- these afferent tracts transmit sensations from visceral organs. such as a full bladder
    • Visceral motor- these efferent fibers exit the CNS and branch to supply nerves to the involuntary cardiac muscle and smooth muscle
  41. Sympathetic hormones
    • Epinephrine(80%)
    • Norepinephrine(20%)
  42. Sympathetic receptors
    • Adrenergic
    • Alpha 1- peripheral vasoconstriction, mild bronchoconstriction, and stimulation of metaabolism
    • Alpha 2- serve to prevent overrelease of norepinephrine in the synapse
    • Beta 1- cause increase heart rate, cardiac contractile force, and cardiac automaticity and conduction
    • Beta 2- cause vasodilation and bronchodilation
    • Dopaminergic- cause dilation of the renal, coronary and cerebral arteries

    • Nicotinic(m)- found at the neuromuscular junction and initiate muscular contraction as part of the somatic nervous system
    • Muscarinic- found in many organs throughout the body and are primarily responsible for promoting the parasympathetic response
  46. Hypothalamus

    Respondes to nerve impluses from hypothalamus

    • Antidiuretic hormone- kidneys (water absorbson)

    • Adrenocorticotropic hormone (ACTH)- Targets the adrenal cortexes

    • Follicle-stimulating hormone (FSH)- targets gonads
    • Luteinizing hormone (LH)- targets gonads
    • Prolactin (PRL)- target the mammary glads in women
    • Growth Hormone (GH)- targets almost all body cells
  50. Thyroid
    two lobes one on either side of trachea

    • Thyroxine(T4)- stimulate cell metabolism
    • Triiodothyronine(T3) stimulate cell metabolism
    • Calcitonin- lowers blood calcium levels
  51. Parathyroid Glands
    normally 4 are located on the posterior lateral surface of the thyroid

    Parathyroid hormone (PTH)- increase blood calcium levels
  52. Thymus gland
    larger in children but shrinks by adulthood

    Thymosin- promotes maturation of T Lymphocytes (responsible for cell immunity)
  53. Pancreas
    contain both endocrine and exocrine tissues

    • exocrine- known as acini secrete digestive enzymes essential to digestion of fats and prooteins
    • Endocrine tissue is known as islets of langerhans three most important endocrine cells are, alpha, beta, delta
    • Alpha and beta produce glucagon, insulin
  54. Glycongenolysis
    the breakdown of glycogen to glucose, primarily by the liver cells
  55. Glucongeogensis
    conversion of protein and fat to form glucose
  56. Outer adrenal glands
    "Adrenal Cortex" - consists of endocrine tissue

    • secretes three classes of steroidal hormones
    • Glucocorticoides
    • Mineralocorticoids
    • Androgenic
  57. Interior Adrenal glands
    • "adrenal medulla" - cells behave as both nerve and gland
    • responsible for secreting epinephrine and norepinephrine
  58. Gonads
    • responsible for the sexual maturation of puberty and repoduction
    • ovaries produce- estrogen and progesterine
    • Testes produce- testosterone
