Topic 1: Introduction to Anatomy and Osteology Flashcards
(43 cards)
define the standard anatomical position
Palms facing forwards
Legs shoulder width apart
Head straight
describe sagittal plane
separates left and right
flexion and extension
describe coronal plane
divides front and back
abduction and adduction
describe transverse plan
divides top and bottom parts
rotation
anterior
towards the front (ventral)
posterior
towards the back (dorsal)
superior
towards the head/top (cephalic)
inferior
towards the feet/bottom (caudal)
medial
towards the midline
lateral
away from the midline
proximal
towards the trunk
distal
away from the trunk
superficial
towards the surface
deep
away from the surface
major bones in the axial skeleton
skull, vertebral column, thoracic cage, laryngeal skeleton
major bones in appendicular skeleton
girdles (shoulder and pelvic), free limbs
functions of the skeleton
support
protection
movement
mineral storage
red blood cell formation
long bones
Longer than they are wide
Have a shaft and two expanded ends
Found in limbs
Examples: humerus, femur
short bones
Roughly equal length and width
No shaft
Found in hands and feet
Examples: carpals, tarsals
flat bones
Thin, flattened bones
Usually form boundaries of cavities to protect underlying structures
Examples: cranial bones (e.g. frontal bone), sternum, ribs, scapulae
irregular bones
Complex, mixed shapes
Do not fit into other categories
Examples: facial bones, vertebrae, hip bones
seasmoid bones
Small, round bones
Develop within tendons
Protect tendon (muscle to bone)
Change the angle of tendon insertion to increase leverage for muscle contraction
Example: patella
trochanter
Large, round projection (only on femur) attachment
tuberosity
Rough projection (e.g. on hip bone/ischial tuberosities) attachment
