a&p exam 5 Flashcards
sympathetic
flight or fight
thoracic and lumbar region of spinal cord
pns-near vetrebal column
short
sends NE or E through the blood stream
parasympathetic
rest and digest
sacral region of spinal cord and base of brain near effector organs
long
Sends ACH through the postglanglionic fiber
adregenaric synapses
responds to NE/E (adreneline)
ALPHA 1 (both 1 and 2 are primarly NE AND SOMETIMES E)
SMOOTH MUSCLE CELLS/ EXCITATION
ALPHA 2
Nuerons, coordinated resposne, inhibition
BETA 1: ALL 3 ARE PRIMARLY E
Increases metabolic activity
BETA 2
Inhibition of smooth muscles in respitory tract. ex: opens up the lungs
BETA 3
Adipose tissue: It breaks down lipids
cholegernic
responds to ACH
Nicotinic
Responds to muscle contractions
on post ganglionic fibers and turns things on by telling the fibers to do it
muscarinic
variable
turn things on in the system +
integument
physical protection. storage if lipids, coordination of immune response, sensory imformation, synthesis of vitamin D3, excretion, thermoregulation.
Intradermal (type of injection)
shallowest
Intravenous
Fastest
Subcutaneous
slow injection for medicine
intramuscular
Used for vaccines
epidermis
protects the dermis, sensory receptors, synthesize vitamin D3 (epethelial tissue)
Dermis
Pappillary
nourishes and supports epidermis and reticular layers (sensory receptors)
accessory structures
Hair follicles, nails, exocrine gland
keratinocytes
cell type in eperdermis, makes keratin
EGF
Protein that involves regulation of cell proliferation
elastic fibers
proteins that allows body to resume shape after stretching/ contracting
melanosomes
organs that synthesize and store melanin
melanocytes
cells that produce pigment (present in stratum basale)
EUmalanin
shades of brown
pheomelanin
shades of orange/ yellow
Albinism
melenocytes cannot be transported to keratinocytes
vitiligo
lose the melocytes in patches
Jaundice
excess billubrum in the blood can affect pigmentation
Recovery from a cut
!.) Bleeding occurs and mast cells trigger a immune response
2.) a scab will form after several hours
3.) After a week the scab has been undermined by epeidermal cells
4.) Connective tissue is healed even though their is a scar there
reticular tissue
Looks like broken spider webs
Loose connective tissue proper
made up of mostly cells
osseus tissue
AKA bone tissue
made up of mostly calcium
protects other tissue from damage
adipose tissue
storage of lipids and fats
blood and lymph
- White blood cells have a nucleus, red blood cells do not.
- Lymph responds to signs of injury and infection
hyaline cartilage
loose connective tissue
found in places like around our joints that need cushion
Fibrocartilage
its dense and holds more weight
pons
relays sensory info to the thalamus and cerrebelum
medulla oblaganta
relays sensory info to thalamus and other parts of brain
midbrain
auditory visual
anaxonic
lots od dendracities , good for hearing
bipolar
very rare, used for special senses
uni polar
for emergencies
multi polar
sends complex actions
