final study guide Flashcards
sagittal plane
plane that divides body into left and right
frontal/coronal plane
divides the body into front and back sections
transverse plane
divides the body into top and bottom
Anatomical position
standing upright with palms facing forward
anterior and posterior
anterior: front of body
posterior: back of body
Abdution and Adduction
Abduction: away from midline
Adduction: towards midline
Superficial and Deep
Superficial: on surface of body
Deep: away from surface of body
Apex and Base
Apex: tip of an organ
Base: bottom/lower part of organ
Prone and Supine
Prone: On stomach, face down
Supine: on back, face up
flexion and extension
flexion: to bend
extension: to straighten
pronation and supination
pronation: turn palm down
supination: palm facing up
Inversion and Eversion
Inversion: turning inward (pigeon toed)
Eversion: turning outward (duck feet)
Internal and External rotation
internal rotation: turning body part inward
External rotation: turning part outward
Horizontal Abduction and Adduction
arms straight out: clapping
Plantarflexion and dorisflexion
plantarflexion: pointing toes
dorisflexion: bringing toes up
functions of skeletal system?
support soft tissue, protect internal organs, movement of limbs, storage of minerals/blood cells, forms blood cells
Types of bones?
long, short, flat, irregular, and sesamoid bones
Long bones
longer than wide- humerus, tibia (arms/legs)
Short bones
wide as they are tall- carpals and tarsals
flat bones
protection- skull, ribs, clavicle, sternum, scapula, and pelvis
irregular bones
vertebrae, sacrum: Make up spine
sesamoid bones
bones in tendons- patella
projection and depressions
projections: attachment sites for muscles
depressions: allow blood vessels and nerves to pass
epiphyseal plate
growth plate
periosteum
tissue surrounding the diaphysis
articular cartilage
smooth, protects bone, no blood supply
medullary cavity
space in bone containing bone marrow
ossification
process of making new bone
osteoBlast
cells the BUILD bone
osteoClast
cells that crush bone
axial skeleton
protection- skull, spine, rib cage, sternum, pelvis
appendicular skeleton
appendages- arms/legs, shoulder/pelvic girdle
what makes up the Shoulder girdle?
sternum (manubrium, body, xiphoid process) , humerus, scapula, clavicle
Acromioclavicular, sternoclavicular, scapulothoracic, and glenohumeral are shoulder girdle what?
shoulder girdle joints.
forearm bones
radius (thumb side) and ulna (pinky side)
Hand bones
carpals (short bones), metacarpals, and phalanges
elbow motions
flexion/extension, pronation/supination
elbow motions
flexion/extension, pronation/supination
wrist motions
flexion/extension, radial/ulnar radiation
lower extremeity bones:
appendicular skeleton
hips and pelvis
Ischium (sit down bones), illium, femur, illiac crest
hip motions:
flexion/extension, internal/external rotation, ab/adduction
knee:
femur makes up hip and knee, patella,
foot:
calcaneus (heel bone)
Tarsal and metatarsal
tarsal- ankle bones (calcaneus)
metatarsals: arch of foot
Phalanges: toes
foot movements
flexion/extension, ankle inversion/eversion, plantar flexion/ dorisflexion
Spine numbers (cervical, thoracic, and lumbar):
cervical: 7 vertebrae, thoracic: 12 vertebrae, lumbar: 5 vertebrae, sacrum, coccyx
C1: atlas
C2: axis
parts of spine:
vertebra, disc, facet joints, spinal cord, nerve roots
movable vs inmovable joints
movable: allow range of movement
immovable: little to no movement
Ribs:
true ribs: attach to sternum in front (7)
false ribs: don’t directly attach to sternum (8-10)
Floating ribs: no attachment to sternum at all (11-12)
Spinal cord:
sends motor signals down from brain, send sensory signals to brain, reflexes
movements of spine
flexion/extension, rotation, side bending (lateral flexion)
Bone fractures:
break in bone
direct vs indirect trauma:
direct: at site where force was applied
indirect: farther from where force was applied
Closed (simple) fracture
break in bone from force, no break in skin
open (compound) fracture
bone breaks completely, break in skin
spiral fracture:
caused by sudden rotation in opposite direction- S-shaped separation
greenstick fracture
incomplete break- occurs in children
