control secretion of hormones from other endocrine glands
Which of the following statments best descibe negative feedback
When blood decreases in osmolarity, ADH release is inhibited
Along with the Nervous system the __ systme coordiantes the various activites of body parts
Endocrine
Which of the following structure in the CNS controls the anterior pituitary galnd
Hypthalamus
Which endocrine gland does not rpoduce the hormone but stores the hormone for release
Par nervosa
___ are chemcials messengers that are produced in one body region but affect a diff body region
Hormones
The receptors for non-steriod protien hormones are on the
Plasma membrane
The posterior pituitary stores and secretes
ADH and oxytocin
Steriod hormone leads to the
Replication of hormones by the cells DNA
Hypothalamus regulates
Heat rate, body temp , water blance and secretions
The fucntion of oxytocin is are to
Cause uterus to contract, induce labor, stimulate relase of milk when nursing, and pheromone in lower animals
Hormones produced by the anterior pitu. that have a direct effect on the body rather than trigger another gland are
GH, prolactin
Growth hormone promotes
Cell division, protien synthesis, bone growth
If ___ is lacking in the diet, thyroid galnd enlarges producing a goiter
Iodine
Parathyroid galnd are located
Imbedded in the posterior surface of the thyroid gland
If thyroid fails to develop properly from childhood a condition called ___ results
Cretinism
Hypothyrodisum in adults produces a condtion called
Myxedema
In addition to thyroxine and triiodothyrorine the thyroid galnd produces
Calcitonin
Calcitonin
Regulates calcium levels, Balanced by action of PTH, increases the deposit of clacium in bone
Parathyroid hormone
Causes blood calcium levels to increase
If insufficient PTH is produced the blood clacium levels drops resulating in
Tetany where the body shakes from continuous muscle contraction
The adrenal gland consisit of
Inner medulla and outer cortex
The adrenal medulla secretes ___ under conditions of stress
Norepinephrine ( noradrenaline)
Epinephrine (Adrenaline)
ACTH Controls the secretion of
cortisol
