Chapter 1 Flashcards
Sagittal Plane
Divides the body into left and right sides.
Flexion and extension.
Ex: Bicep Curls
Frontal Plane
Divides the body into anterior and posterior sides.
Abduction and adduction.
Ex: Jumping Jacks
Transverse Plane
Divides the body into upper and lower parts.
Rotation.
Ex: Pitching, Wood chops
Frontal Axis

Transverse Plane
Joints
Any point where two bones meet
Classified by structure and function, and sometimes these classifications overlap
Arthroses
Joints that have no motion
Fibrous Joints
Immovable or slightly movable joints
Ex: Tibia/Fibula
Cartilaginous Joints
Joined by hyaline cartilage
Ex: R/L pubic bones
Synovial Joints
Freely movable
Ex: Phalanges
Synarthrodial Joints
Immovable
Ex: Skull
Amphiarthrodial Joints
Slightly movable joints
Ex: R/L pubic bones
Diarthrodial Joints
Freely movable
Ex: Phalanges
Goniometer
Device used to measure specific amount of movement possible in a joint
Abduction
Lateral movement away from the midline
Adduction
Movement medially toward the midline
Flexion
Bending movement that results in a decrease of the angle in a joint by bringing bones together
Extension
Straightening movement that results in an increase of the angle in a joint by moving bones apart
External Rotation
Rotary movement around the longitudinal axis of a bone away from the midline
Internal Rotation
Rotary movement around the longitudinal axis of a bone toward the midline of the body
Eversion
Turning the sole of the foot outward/laterally
Inversion
Turning the sole of the foot inward/medially
Dorsiflexion
Flexion movement of the ankle (toes up towards tibialis anterior)
Planter Flexion
Extension movement of the ankle (raised up on toes)
Pronation
Palms down
ankle dorsiflexion + subtalar eversion + forefoot abduction
Supination
Palms up
ankle plantar flexion + subtalar inversion + forefoot adduction
