Sciatic
| Question | Answer |
|---|---|
| nerve is the body's longest and thickest beginning in the buttocks all the way to the feet | Sciatic |
| in the abdomen is such a site where thousands of peripheral nerve fibers intermingle before branching outward to internal organs, arms, legs | Solar Plexus |
| control conscious, voluntary movement by sending information to skeletal muscles ex. combing hair | somatic (voluntary) |
| control all internal organs and their processes such as breathing and digestion. control unconscious, involuntary functions such as heart rate, hormone secretion. automatically alert without being aware of it | Autonomic (involuntary) |
| increase mobilize organ function when needed, speed up heart or breathing rates | Sympathetic Autonomic Nerve |
| decrease organ/gland function when needed, returning organs to a quiet, calm state. activate when rest, sleep, relaxation is needed | Parasympathetic Autonomic Nerves |
| 12 pair of nerves that originate and extend directly from the under surface of the brain | 12 cranial nerves |
| smell; is the only part of the brain exposed to the outside world and the only nerve connected directly to the cerebrum hemisphere | Olfactory |
| vision (25% of brain is devoted to this) | Optic |
| face, teeth, tongue, chewing, tears, lips, scalp, gums (associated with migraine headaches) | Trigeminal |
| "feel good" brain chemical is associated with headaches, dilates & inflames blood vessels; | Serotonin |
| very sensitive nerve in the roof of the mouth and should extreme cold touch the upper roof, this nerve over reacts and screams | Spheno-Palatine Ganglion |
| collection of 9 glands located throughout the body that produce Hormone, twin brother of the nervous system | endocrine system |
| complex, extremely potent chemical messengers that, when needed, diffuse out of their respective gland into the bloodstream for transport to a "target" site in another part of the body | Hormone Physiology |
| regulates hormone levels/amounts. receptors that sense change | Feedback Mechanism |
| cherry-sized. endocrine and nervous system key site. coordinate and control hormone secretion | Hypothalamus |
| remarkable pea-sized gland located about an inch behind the nose that's attached to, and hangs down from, the base of the Hypothalamus | Pituitary gland |
| bigger, produces 7 hormones | Anterior Lobe |
| "central commander master" because it secretes 9 distinct hormones. housed in a safe well protected depression of the Sphenoid inner skull bone | Pituitary gland |
| produces 2 hormones | Posterior Lobe |
| located deep in the exact center of the brain between the two hemispheres. | Pineal gland |
| pineal gland produces this; regulates sleep patterns because it senses light- exposure as in night and day | Melatonin |
| largest endocrine glands, located in the neck in front of the trachea windpipe just below the Adam's Apple; shaped like a bow-tie and has two lobes connected by an isthmus connecting tunnel key role is metabolism | Thyroid Gland |
| regulates metabolism, which is how quickly the body burns energy. determines how energetic we are | Thyroxin (T-4) |
