Prone
Face Down
Supine

Ipsilateral
Same side
Contralateral
Opposite sides
Extension
Motion that increase an angle of a joint pushing the body part away from the body (open fist)
Flexion
bending motion that decreases the angle eturning the body part to the body (closed fist)
Adduction
Movement toward the midline
Abduction
Movement away from the midline
Medial Rotation
Rotation movement toward the midline
Lateral Rotation
Rotation movement away from the midline
Rotation
Occurs only in the spine on transverse plane. Turning the spinal column
Circumduction
circular movement at a ball and socket joint (shoulder)
Lateral Flexion
the movement of a body part in the lateral direction, sidewards. The lateral flexion concerns mainly torso or neck and can be performed either to the right or to the left side
Supination
Turning the palm up or forward
Pronation
Turning the palm down or backward
Opposition
thumb is rotated around its long axis. only the thumbs can perform opposition
Inversion
Turning inward in reference to the foot
Eversion
Turning outward in reference to the foot
Plantar Flexion
Bending the foot so the toes point downward
Dorsiflexion
Bending the foot upward to the ankle
Protraction
the act of moving an anatomical part forward
ex: your jaw
Retraction
the act of drawing back, or condition of being drawn back
Ex: your jaw
Elevation
Upward movement of a limb or body part
Depression
Downward movement of limb or body part (opening mouth)
Deviation
Moving side to Side
Ex: Mandible
Costal
Ribs
Composed of bone, cartilage and ligaments
Protects and supports body organs
Provides framework for muscles
site of blood cell formation and stores minerals
Skeletal system
3 types of cartilage
Hyaline (end of joints and nose)
Elastic (ears and epiglottis)
Fibro (spinal discs, knees, and pubic symphysis)
Bones of the skull, vertebral column, hyoid, and ribcage
Consists of 80 bones
Axial skeleton
Bones of the upper and lower limbs, shoulder, and hips
Consists of 128 bones
Appendicular Skeleton
3 functional classes of joints
Synarthroses (immovable)
Amphiarthroses (slightly movable)
Diarthroses (freely movable)
Functional Joint
based on the amount of movement allowed by the joint
Structural joint
material binding bones together and whether or not a joint cavity is present
3 structural classes of joints
fibrous (suture, syndesmosis, gomphosis)
cartilaginous (synchondroses, symphyses)
Synovial (Diarthrotic joint)
Composed of muscle and tendon
allows manipulation of environment, locomotion and facial expression
maintains posture, produces heat
Muscular system
Name a Gliding joint
Carpals, tarsals, costal ribs, facet joint
Name a hinge (ginglymus) joint
elbow, phalanges, knee, interphalangial joint, temporomandibular joint (TMJ joint)
Name a pivot (trochoid) joint
forearm between radius an ulna, between C1+C2
Name a Condyloid (ellipsoid) joint
knuckles and wrist
Name a saddle (seller) joint
thumb
Name a ball and socket joint
Shoulder and hip
composed of heart and blood vessels
heart pumps blood
Vessels (arteries and veins) transport blood
closed system
Cardiovascular system
composed of brain spinal cord and nerves
Control system of the body
responds to stimuli by activating muscle and glands
Nervous system
3 nervous system functions
sensory input - monitoring stimuli
integration - interpretation of input
motor output - response to stimuli by activating organ response
name 2 parts of the central nervous system
Brain, spinal column
Carries message to and from spinal cord to the brain
peripheral nervous system
Composed of red bone marrow, thymus, spleen, lymph nodes and lymphatic vessels
picks up fluid leaked and returns it to blood
dispose of debris in lymphatic system
houses white blood cells
open system
Lymphatic system
Ball-and-Socket joint
a spherical surface bone fits into a dish shaped depression of another bone
Ellipsoid joint
oval shaped end of one bone articulating with an elliptical basin of another bone.
Hinge joint
similar to a door hinge
Saddle joint
modifies ellipsoid joint composed of a convex and concave articulating surfaces
gliding joint
two flat surfaces, with small shifting movement like the carpal bones
Pivot joint
designed to allow one bone to rotate around the surface of another bone
