Physiology 2: III to VI Flashcards
Area in Front of the Central Sulcus
Motor Area
Motor speech area that coordinates muscles in mouth, tongue and larynx
Broca’s Area
Sensory area that interprets sensations of pain, pressure, temperature and touch
Parietal Lobes
Sensory area that interprets vision
Occipital Lobe
Sensory area that interprets hearing
Temporal Lobes
Masses of gray matter deep within the cerebral hemisphere that relay motor impulses
Basal Nuclei
Neurotransmitter that basal nuclei use to inhibit motor impulses
Dopamine
System that controls emotional behavior that may increase the chance of survival
Limbic System
(top to bottom) Part of the Brain Stem
- Midbrain
- Pons
- Medulla Oblongata
When sensory information reaches it, it awakens the cerebral cortx
Reticular Formation
Integrates sensory information regarding body position and coordinates muscle activity
Cerebellum
Action of a hormone is restricted to what?
Target Tissue/Cells
What attaches the pituitary gland to the hypothalamus
Infundibulum
Growth Hormone and Thyroid Stimulating Hormone are secreted from where?
Anterior Lobe of the Pituitary Gland
Antidiuretic Hormone and Oxytocin are secreted from where?
Posterior Lobe of the Pituitary Gland
Hormones secreted from the thyroid gland that regulate metabolism and require iodine
- Thyroxine
- Triiodothyronine
Hormone secreted from the thyroid gland that lowers blood calcium and phosphorous
Calcitonin
Hormone secreted from the parathyroid glands that increases calcium and decreases phosphorous (i.e., stimulates bone resorption)
Parathyroid Hormone
Part of the adrenal glands that secrete norepinephrine and epinephrine
Adrenal Medulla
Part of the adrenal glands that secrete aldosterone, cortisol, adrenal androgens
Adrenal Cortex
Stress hormone secreted by the adrenal cortex that regulates blood glucose
Cortisol
Hormone secreted by the adrenal cortex that K+ and Na+ concentration
Aldosterone
Sex hormones secreted by the adrenal cortex
Adrenal Androgens
Hormone secreted by the pancreas that increases blood glucose levels
Glucagon
Hormone secreted by the pancreas that decreases blood glucose levels
Insulin
Cardiac, vasomotor, and respiratory center located in the brainstem
Medulla Oblongata
Systems that keep concentrations of most hormones relatively stable
Negative Feedback Systems
