Definition
Sagittal plane
Frontal (coronal) plane
Transverse (cross-sectional, axial, or horizontal) plane
Movement in a plane rotates on axis with 90° relationship to plane
Term

rest of bones
Term
Skeletal Muscle
Definition
Muscle primarily attached to bone.
Term
Cardiac Muscle
Definition
Muscle that makes up the heart.
Term
Smooth Muscle
Definition
Lungs,etc.
Term
Muscle types
Definition
Skeletal,Cardiac and Smooth Muscle.
Term
Bursa
Definition
Fluid filled sacks in joints.
Term
Parallel Muscle
Definition
Muscle fibers that run in-line with pull of muscle.
Term

Often described by spatial movement pattern in relation to the body
Often described in terms of anatomical position
Term
Bone Structure
Definition
Diaphysis,Medullary cavity,Epiphysis and Metaphysis
Term
Diaphysis
Definition
Shaft of bone
Term
Medullary cavity
Definition
Endosteum lines medullary cavity
Contains cells for bone development
Term
Epiphysis
Definition
Bone ends covered by articular cartilage
Term
Metaphysis
Definition
diaphysis meets epiphysis
Region of mature bone
Term
Periosteum
Definition
covering on surface of bones
2 layers
Serves as attachment point for
ligaments and tendons
Critical for bone growth, repair, nutrition
Term
Long Bone
Definition
Femur,Tibia,Humerus,Ulna,Radius
Term
Short Bone
Definition
Carpals,Tarsals
Term
Flat Bone
Definition
Sternum,Scapulae,Ribs,Pelvis
Term
Irregular Bone
Definition
Vertebrae,Sacrum,Coccyx
Term
Sesamoid
Definition
Patella
Term
Synarthrodial
Definition
Joint doesn't not move
Term
Amphiarthrodial
Definition
Joint moves slightly
Term
Diarthrodial (synovial)
Definition
Joint moves freely
Term
Synovial Joints Features
Definition
Fibrous joint capsule
Capsule encloses joint cavity
Joint cavity lined with synovial membrane
Synovial fluid occupies joint cavity
Articulating surfaces of bones covered by hyaline cartilage
Helps body absorb shock and reduces friction
Term
Open chain exercise
Definition
distal segment of a joint moves in space
Ex: leg extension on a machine
Term
Closed chain
Definition
movement occur when distal segment of joint is fixed in space
Ex: standing barbell squat
Term
Closed pack
Definition
both maximal congruency of the joint surfaces and maximal tautness of the joint capsule and ligaments
Term
Open pack (loose)
Definition
there is the least joint congruency and the joint capsule and ligaments are loose
Term
Pelvis and Hip Bones are?
Definition
Sacrum,Fused ilium (largest pelvic bone) Ischium,Pubis on each side (usually fuse by puberty)
Term
Pelvic griddle allows movement in what 3 planes ?
Definition
Rotation-transverse plane
Lateral tilt frontal plane
Anterior and posterior tilt sagittal plane.
Term
Hip joint allow which type of movements.
Definition
extension sagittal plane

Abduction/adduction frontal plan

Internal/external rotation

Flexiontransverse plane

Circumduction of combined plane movements
Term
spinal column contains complex of irregular bones, How many bones are their.
Definition
