The glands and cells of the endocrine system secrete chemicals called
(a)
(a) glands are ductless glands. They secrete hormones directly into the bloodstream.
(a) glands secrete hormones into ducts, which in turn, lead to a surface in some other location such as the body's surface or the digestive tract.
One of the classifications of hormones that are synthesized form cholesterol; pass easily through a cell's membrane. fat soluble. include male and female sex hormones and aldosterone (secreted by the adrenal cortex)
steroid hormone
nonsteroid or protein-based hormone
One of classifications of hormones that synthesize(insulin), peptide, and amino acid derivative hormones (epinephrine and norepinephrine). Don not pass the cell membrane easily. bind to receptors on the cell surface.
Steroid hormoned
nonsteroid or protein-based hormone
Gland that sits underneath the hypothalamus. It lies cradled in the sella turcica, a cavity within the sphenoid bone
Adrenal gland
pineal gland
Pituitary gland
Thyroid gland
The stalk that connects the hypothalamus and pituitary
sella turcica
infundibulum
Medulla oblongata
Pineal gland
Match the following hormones released by the anterior pituitary
(TSH)Thyroid Stimulating Hormone
Stimulates thyroid to produce thyroid hormones
prolactin
milk production
Adrenocorticotropic Hormone (ACTH)
stimulates cerebral cortex to release corticosteroids
Growth hormone (GH)
protein synthesis, carb metabolism, bone and skeletal muscle growth
Stim ovulation & estrogen synthesis
Luteininzing
Follicle Stimulating Hormone (FSH)
production of eggs and sperm
(ADH) Antidiuretic hormone
Water retention in kidneys
(OT) Oxytocin
stimulates uterine contraction
Made up of glandular tissue, This is the larger part of the pituitary that secretes very important hormones under the direction of the hypothalamus
Adenohypophysis (Anterior Pituitary)
Neurohypophysis (posterior pituitary)
Thalamus
Medulla Oblongata
Made up of neural tissue, This smaller part of the pituitary simply stores hormones synthesized by the hypothalamus
Adenohypophysis
(Anterior pituitary)
Neurohypophysis (posterior pituitary)
Thyroid gland
Pancreas
Hypersecretion of growth hormone during a child's growth years will trigger rapid excessive skeletal growth, resulting in Gigantism. Hyposecretion will result in stunted growth called pituitary dwarfism.
true
false
Negative feedback is a process by which;
a hormone is fed back to the pituitary, telling it to stop further release of that hormone.
the deficiency of a certain hormone stimulates a gland to release more of that hormone.
the central nervous system monitors the conditions inside and outside of the body and, in turn, triggers the release of hormones as needed.
hormone levels fall precipitously, triggering shock
he nerve fibers that form the posterior pituitary originate in the
(a)
Inner portion of the adrenal gland that consists of modified neurons and functions as part of the sympathetic nervous system. secretes Catecholamines epinephrine and norepinephrine
Adrenal Medulla
Adrenal Cortex
Glandular tissue and outer portion of the adrenal gland. Secretes corticosteroids.
adrenal medulla
adrenal cortex
A key difference between the anterior and posterior pituitary is that the posterior pituitary:
consists of glandular tissue
secretes hormones under the direction of the hypothalamus
receives hormones from the hypothalamus via the hypophyseal portal system.
stores hormones released from the hypothalamus.
When a stressful event occurs, the amygdala in the brain signals hypothalamus to activate the sympathetic nervous system. After 10 seconds the
hypothalamic-pituitary-adrenal axis (HPA) is stimulated to help the body cope
true
false
Gland that produces melatonin, which rises a night. triggering sleepiness. regulate timitucked in the center of the brain on the roof of the brain's third ventricle. ng of puberty.
pineal gland
adrenal gland
hypothalamus
thalamus
mood disorder occurring during the winter months when exposure to sunlight is limited.
Seasonal Affective Disorder
Cushing syndrome
Addisons disease
Winter Anxiety
