RANDOM BLACBOOK Flashcards
What is anatomy?
sci - sructure - reln to its parts
What constitutes structure?
skeleton- bony framework
protects- gives shape- plsce for attachment
What is physiology
study of fx
What is a tissue
grp / layer of similar specialized cells - perform specialized fx
histology
study of strcture / arrange of tissues
CLASSIFICATION OF TISSUES
epithelial
connective
muscular
nervous
continuous layer - cover body surface / lining body cavity
fx: seucretion-absorption-secretion-sensation
epithtelial
supports + holds together other cells
Give examples
Connective tissue
Ex
bone
cartilage
tendon
ligament
fibrous ct
non living material
secreted by cells of ct
becomes bonding & supporting matl b\n cells
matrix
controls contractions of muscles
Composition?
Types?
- Muscular t
-elongated cylindrical - spindle shaped cells -small longt // contractile fibers
-skeletal
smooth
cardiac m
- fx: conduction of electochmical nerve impulses
- Why neuron cells join together
nervous tissue
-to pass impulses over long dist -body
what is mitosis
reg division of cells
ability to renew itself- growth of tiss - due to multiolication of cell members
each 2 resultant cell same # & chromos of parent
describe cell structure (7)
protoplasm - gelatin; mass of cell (protein mol-fatty matls-carbo-salts)
plasma memb- outer surf of cell; elastic cover ; regs passing of contents (nuutrients- waste-secretions)
nucleus - directs cell acts- genes-traits ; granules (chromatin)
nuclear membrane - sep from rest - regs matls in out nucleus
cytoplasm - senuifluuuid matl (drroplets, vacuuoles, granules, fibrils)
centrioles - small cylind adj to nucleus - role in cell division
endoplasmic reticula - tubuular strand - small spaghetti spread outu from cytoplasm
What is an organ
single unit of a system conp of variouusu tiss perform particular fx
what is a system
group of organ - division of labor
circulatory system
transport matls throughout body
Respiratory system
provides exchange off oxygen and co2
digestive system
provides for
intake - breakdown-absorption of food
excretory system
elimination of waste
skeletal system
body locomotion & support
muusccular system
mvmt & locomotion in conjuction w skeletal sys
nervvous system
conduucts impulses around body
& integrates activities of systems
endocrine system
coordinator of body fx
reproduuctive system
continuation of species
sensory system
receives stimuli in & out of body
what factors detss density of tissue amd organs
dep on composition of cell structure - solid -empty-filled
Skin fx
- protect form envt bacteria
-maintain internal envt
-shields blows-friction-rpressure
-waterproof
-protect from uuv - suntan - thermostat - control elim of heat / insulation
- excretoryy -thruu sweat glands
- contain- sense receptors - feel pressure &U temp-pain - discctim b/n objec
describe strucuuutre of bone
PERIOSTEUM = vasuular - bvs at end covering bone ; - inner layer lined in growing bone
contains OSTEOBLAST (bone forming cells)
CORTEX - uunder periosteum; comp: dense compact bone
CANCELLOUS BONE - inner spongy, porous section froming a layer under a cortex
MEDULLA -cavity of shafft bone
ENDOSTEUM - lining of bone cavity
BONE MARROW - tissue contained w/in cavity of long bone
*YELLOW BONE MARROW - adult; muuo FAT
* RED BW - lil fat; supplied w blood & ERHYTHROBLAST (reddish colored cells) ; where RBC fromed
NUUTRIENT FORAMINA - small opening - bv - nutrient artery
BONE CLASSIFICATION
LONG BONES = 2 extremities & shaft; provided w medullary canal - contains marrow
SHORT BONES - small irregular shaoe ; muo cancellous tissue ; compact issue - surface
FLAT BONES = extensive protection and broad surfaces – for muscle attach
IRREGULAR BONE= peculiar shape - vertebra
Explain
DIAPHYSIS
EPIPHYSIS
EPIPHYSEAL LINE
METAPHYSIS
DIAPHYSIS = middle; pmry center of ossification
EPIPHYSIS = ends ; secondary center of ossif
EPIPHYSEAL LINE = thin cartilge sep diaphysis and epiphysis
METAPHYSIS = middle of epiphysis and diaphysis
JOINT CLASIFICATION
Immovable/fibrous = permit no mvmt; ossified later; skull
Slightly movable/ cartilogenous joint = where cartilage unite the bone;hard hyaline +disk of s9fter fibrocartilage ;limited motion; vertebra
Freely movable /Synovial joint = smooth articulsr cartilage ; oiled by synovial fluid
TYPES OF FREELY MOVING JOINTS
GLIDING = slides; no rotation; vertebra, intercarpal
HINGE = w angular mvmt; elbow bending
SADDLE = 2 angular mvmts @ right angle; b&f s&s ; CPMJ Thumb
PIVOT = rotate; ulna-annular (stabilisze ulna to elbow)
BLL ND SOCKET = hip, shoulder; fit to concave
CONDYLOID = circumduction; metacarp j
AXIAL VS APPENDICULAR
AXIAL = SVRS
skull
Vertebrae -33 sep vbones
Ribs 1-7 st 8-10 byc 11-12
Sternum
APPENDICULAR = ULPS

MUSCLE FX
Movmt (contraction-pulling)
Maintain posture
Support joints
Pomote quick mvmt
What is: MUSCLE TONUS ?
Fully relaxed muscle may contract to approx half is length but retain full state of tension
SYSTOLIC VS DIASTOLIC PRESSURE
Systolic = highest pressure (contraction heart)
Diastolic = lowest (relaxing)
Where to exedent attempt to find pulse
RUSF
Radial artery = lat ant wrist
