1 Anatomical Directions & Movements Sports Medicine I
2 Anatomical PositionIn this position, the body is erect with feet together and the palms face forward and the thumbs are pointed away from the body.
3 Anatomical Directions These are used to explain precisely where one body structure is in relation to another.These directional terms refers to an individual’s body as if it were in anatomical position, regardless of its actual position.
4 Anatomical Directions Superior (cranial)Toward the head end or upper part of a structure or the body; Above
5 Anatomical Directions Inferior (caudal)Away from the head end or toward the lower part of a structure or the body; Below
6 Anatomical Directions Anterior (ventral)Toward or at the front of the body; In front of
7 Anatomical Directions Posterior (dorsal)Toward or at the back of the body; Behind
8 Anatomical Directions MedialToward or at the midline of the body; On the inner side of
9 Anatomical Directions LateralAway from the midline of the body; On the outer side of
10 Anatomical Directions ProximalCloser to the origin of the body part or the point of attachment of a limb to the body trunk
11 Anatomical Directions DistalFarther from the origin of a body part or the point of attachment of a limb to the body trunk
12 Anatomical Directions SuperficialToward or at the body surface
13 Anatomical Directions DeepAway from the body surface; More internal
14 Joint Movements There are 3 general types of movements: Gliding Angular movementsRotation
15 Gliding Movements They are the simplest type of joint movement. One flat, or nearly flat, bone surface glides or slips over another similar surface.The bones are merely displaced in relation to one another.
17 Gliding MovementsThey occur at the intercarpal (wrist), intertarsal (foot), intervertebral (spine), and sternoclavicular (sternum meets collarbone) joints.
18 Angular MovementsThese change (increase or decrease) the angle between 2 bones.They include flexion, extension, abduction, adduction & circumduction.
19 Angular Movements Flexion This is a bending movement that decreases the angle of the joint and brings the 2 articulating bones closer together.Flexion of the ankle so that the superior aspect of the foot approaches the shin is called dorsiflexion.
21 Angular Movements Extension This is the reverse of flexion and occurs at the same joints.It involves movement that increases the angle between the articulating bones.
22 Angular MovementsBending the head backward beyond the upright position is called hyperextension.In the foot, extension or straightening of the ankle (pointing one’s toes) is referred to as plantar flexion.
23 Angular Movements Abduction This is movement of a limb away from the midline of the body.When the term is used to indicate the movement of the fingers or toes, it means spreading them apart.
30 Special MovementsCertain movements occur only at specific joints or areas of the body.Supination & pronation refer only to the movements of the radius around the ulna.
31 Special MovementsSupination is the movement of the forearm so that the palm faces anteriorly or superiorly.In the anatomical position, the hand is supinated and the radius & ulna are parallel.In pronation, the palm is moved to a posterior- or inferior-facing position.
35 Special MovementsProtraction & retraction are nonangular anterior and posterior movements.The lower jaw is protracted when you jut it out and retracted when it moves posteriorly & returns to its original position.
