1Anatomical Directions & Movements Sports Medicine I
2Anatomical PositionIn this position, the body is erect with feet together and the palms face forward and the thumbs are pointed away from the body.
3Anatomical 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.
4Anatomical Directions Superior (cranial)Toward the head end or upper part of a structure or the body; Above
5Anatomical Directions Inferior (caudal)Away from the head end or toward the lower part of a structure or the body; Below
6Anatomical Directions Anterior (ventral)Toward or at the front of the body; In front of
7Anatomical Directions Posterior (dorsal)Toward or at the back of the body; Behind
8Anatomical Directions MedialToward or at the midline of the body; On the inner side of
9Anatomical Directions LateralAway from the midline of the body; On the outer side of
10Anatomical Directions ProximalCloser to the origin of the body part or the point of attachment of a limb to the body trunk
11Anatomical Directions DistalFarther from the origin of a body part or the point of attachment of a limb to the body trunk
12Anatomical Directions SuperficialToward or at the body surface
13Anatomical Directions DeepAway from the body surface; More internal
14Joint Movements There are 3 general types of movements: Gliding Angular movementsRotation
15Gliding 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.
17Gliding MovementsThey occur at the intercarpal (wrist), intertarsal (foot), intervertebral (spine), and sternoclavicular (sternum meets collarbone) joints.
18Angular MovementsThese change (increase or decrease) the angle between 2 bones.They include flexion, extension, abduction, adduction & circumduction.
19Angular 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.
21Angular 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.
22Angular 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.
23Angular 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.
30Special 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.
31Special 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.
35Special 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.
