Term
| Describe the structure & function of the spinal cord |
|
Definition
Gray Matter in the center -> myelinated axons.
ventral root, posterior root
spinal ganglion= sensory neurons
cervical=8 lumbar=5 thoracic=12 sacral= 5 coccyx=1 |
|
|
Term
| Name the major parts of the autonomic nervous system (Centers & divisions) |
|
Definition
| Enviromental influence thoughts -> cerebrum -> hypothalamus (Lymbic system changes in temp)-> meduallary autonomic centers - sympathetic & parasympathetic |
|
|
Term
| List five principles of autonomic function |
|
Definition
1. all reflexive
2. all subconscious
3. maintaining homeostasis
4. dual innervation
5. summation (by effector tissue) |
|
|
Term
| Distinguish the parasympathetic and sympathetic division of the autonomic nervous system in at least 3 ways |
|
Definition
Para-> CNS emergence, cranial + sacrospinal nerves
Sympathetic->Thoracolumbar emergenc from the CNS
Ganglia loeation
Chem. released & dominance - high stress |
|
|
Term
| Describe the nervous system disorders |
|
Definition
Myasthanian Gravis- drug to treat it called neostigmine that blocks acteyloesterasecholine
Plasmaphoresis-allows electrical separation
Alzheimer disease- affect 10%of all people over 65 amyloid plauges accumulated in cells |

|
Term
| Describe the structure & function of all parts of the eye (including the 6 extrinsic muscle) and name/identify the abnormal conditions covered in lecture |
|
Definition
| eye receptors are in the retina, the are called rods ->110 million per eye and cone cells -> 7-10 million per eye color division |
|
|
Term
| Ear structure & abnormal conditions |
|
Definition
|
|
Term
| What are the endocrine glands & hormones (what do they control?) |
|
Definition
Endocrine glands-ductless glands secreting chem signs into the circulatory system
hormones- chem signals secreted by endocrine glands can be chem categorized as belonging to the "protein group" or the "lipid group" |
|
|
Term
| Biochem classes of horomones |
|
Definition
| Membrane (bound receptors) extend across the plasma membrane and have their receptor sites exposed to the outer surface of the plasma membrane. Hormones that bind to the membrane-bound receptors are large molecules and water- soluble molecules that cannot pass through the plasma membrane, they are proteins, glycoproteins, polyeptieds & some smaller molecules such as epinephrine & nonepinephrine |

Term
|
Definition
| Intracellular receptors- in the cytoplasm or in the nucleus of the cell. hormones that diffuse through the plasma membrane bind to the intracellular receptors and the hormone -receptor complex & then initiates the cell's response. These hormones are lipid soluble& relativity small. Thyroi, steriod->testosterone, estrogen, progesterone, aldosterone & orisol |
|
|
Term
| Three major endocrine glands |
|
Definition
Pineal Gland
Pituitary gland
Parathyroid gland
*Look Up |
|
|
Term
| Name or identity endocrine disorders |
|
Definition
Growth hormone
Giganticism - 6'11 to 8' hypersecretion, after adulthood = acromegley
dwarfism hyposecretion, short but evenly proportional
congenital = pituitar, choridro dystropohic dwarfism |
|
|
Term
| structures & functions of the respiratory system |
|
Definition
oxygenates the blood* - it removes CO2 "gas exchange"
Gas exchange- respiratory & card. systems work together to supply oxygen to all cells and remove carbon dioxide
Reg. of blood PH- the respiratory system can alter blood PH by changing blood carbon dioxide levels
Voice Prod.- air movement past the vocal folds makes sound & speach possible
olfaction-sensation of smell happens when airborne molecules are drawn into nasal cavity
protection-the respiratory system provides protection against some microorganisms by preventing their entry into the body & by removing them from respiratory surfaces |
|
|
Term
| describe breathing & air pressure & volume changes that allow inspiration & expiration |
|
Definition
inspiration- abd muscles are relaxed= diaphragm, & muscles that elevate the ribs & sternum (external intercortals, pectoralis minor & scalenes)
Expiration- muscles that depress the ribs & sternum, such as the abd muscles & the internal intercostals
Normal- respiratory muscles are relaxed
labored- all inspiratory muscles are are active & they contract more forcefully than during quite breathing, causing a greater increase in thoracic volume |
|
|
Term
| Describe relationship between the hypothalamus & pituitary |
|
Definition
Hypothalamus & pituitary gland are major sites where the nervous & endocrine systems interact. Pituitary secrets 9 major hormones that regulate numerous body functions & the secretory activity of several other endocrine glands
The hypothalamus regulates the secretory activity of the pituitary gland |
|
|
Term
| list 6 secretions & describe effects |
|
Definition
1. Antidiuretic hormone-increase water re absorption
2. oxytocin-increase uterine contrations; milk explusion from mammary glands; unclear function in males.
3. growth horomoe- increase growth in tissues
4. thyroid- stimulation hormone, incrase theyroid hormone secretion
5.Melanocyte- stimulatoin hormone increased melanin production in melanocytes to make skin color darker
6. prolactin- milk production in lactating in women |
