Please answer the following short answer questions:
1. Name the 3 planes of motion and describe their importance in working with human movement. sagittal, frontal, and transverse.
The sagittal plane divides the body into the left and right side. The frontal plane divides the body front (anterior) and back (posterior) portions. The transverse plane divides the body into the upper (superior) and lower (inferior) portions.
Sagittal:
Flexion: Decreasing the angle between two bones
Extension: Increasing the Angle between two bones
Dorsiflexion: Moving the top of the foot toward the shin (only at the ankle)
Plantar flexion: moving the sole of the foot downward (pointing the toes)
Frontal:
Adduction: Motion toward the midline
Abduction: Motion away from the midline of the body
Elevation: Moving to a superior position (only at the scapula)
Depression: Moving to an inferior position (only at the scapula)
Inversion: Lifting the medial border of the foot
Eversion: Lifting the lateral border of the foot
Transverse:
Rotation- Internal (inward) or external (outward) turning about the vertical axis of the bone
Pronation- Rotating the hand and wrist medially from the bone
Supination-Rotating the hand and wrist laterally from the bone
Horizontal Flexion (adduction)- From the 90-degree abducted arm position, the humerus is flexed (adducted) in toward the midline of the body in the transverse plane
Horizontal Extension(abduction)- Return of the humerus from horizontal flexion.
2. Name the 3 axes of motion and each axis' corresponding plane of motion.
Sagittal axis - passes horizontally from posterior to anterior and is formed by the intersection of the sagittal and transverse planes.
Frontal axis - passes horizontally from left to right and is formed by the intersection of the frontal and transverse planes.
Vertical axis - passes vertically from inferior to superior and is formed by the intersection of the sagittal and frontal planes.
