CHAPTER 3 Flashcards
Kinesiology
The study of mechanics of human movement and specifically evaluates muscles, joints, and skeletal structures and their involvement in movement
What are the 3 fields of science kinesiology is based on
Biomechanics
Musculoskeletal anatomy
Neuromuscular physiology
Anatomical position
The universally accepted reference position used to describe regions and spatial relationships of the human body and to refer to body positions ( Ex: joint motions)
Sagittal plane
Divides the body or structure into the right and left sides
Frontal plane (Coronal plane)
Divides the body or structure into anterior and posterior portions
Transverse plane (Cross-sectional, axial, or horizontal plane)
Divides the body or structure into superior and inferior portions
Center of gravity
A theoretical point where the weight force of the object can be considered to act
Line of gravity
An imaginary vertical line passing through the center of gravity and is typically assessed while the subject is standing
Anterior
Front of the body; ventral
Posterior
Back of the body; dorsal
Superficial
Located close to or on the body surface
Deep
Below the surface
Proximal
Closer to any reference point
Distal
Farther from any reference point
Superior
Toward the head; higher (cephalic)
Inferior
Away from the head; lower (caudal)
Medial
Toward the midline of the body
Lateral
Away from the midline of the body; to the side
Ipsilateral
On the same side
Contralateral
On the opposite side
Unilateral
One side
Bilateral
Both sides
Prone
Lying face down
Supine
Lying face up
Valgus
Distal segment of a joint deviates laterally
Varus
Distal segment of the joint deviates medially
Arm
Region from the shoulder to elbow
Forearm
Region from the elbow to wrist
Thigh
Region from the hip to knee
Leg
Region from the knee to ankle
Biomechanics
The study of the motion and causes of motion of living things, using a branch of physics known as mechanics
Joint movement
Described by its spatial movement pattern in relation to the body, typically in terms of anatomical position
Flexion
Movement resulting in a decrease of the joint angle, usually moving anteriorly in the sagittal plane
Extension
Movement resulting in an increase of the joint angle, usually moving posteriorly in the sagittal plane
Abduction
Movement away from the midline of the body, usually in the frontal plane
Adduction
Movement toward the midline of the body, usually in the frontal plane
Horizontal abduction
Movement away from the midline of the body in the transverse plane
Horizontal adduction
Movement toward the midline of the body in the transverse plane
Internal (medial) rotation
Rotation in the transverse plane toward the midline of the body
External (lateral) rotation
Rotation in the transverse plane away from the midline of the body
Lateral flexion
Movement away from the midline of the body in the frontal plane
Rotation
Right or left rotation in the transverse plane
Elevation
Movement of the scapula superiorly in the frontal plane
Depression
Movement of the scapula inferiorly in the frontal plane
Retraction
Movement of the scapula toward the spine in the frontal plane
Protraction
Movement of the scapula away from the spine in the frontal plane
Upward rotation
Superior and lateral movement of the inferior angle of the scapula in the frontal plane
Downward rotation
Inferior and medial movement of the inferior angle of the scapula in the frontal plane
Circumduction
A compound circular movement involving flexion, extension, abduction, and adduction, circumscribing a cone shape
Radial deviation
Abduction of the wrist in the frontal plane
Ulnar deviation
Adduction of the wrist in the frontal plane
Opposition
Diagonal movement of thumb across the palmer surface of the hand to make contact with the 5th digit
Eversion
Abducting the ankle
Inversion
Adducting the ankle
Dorsiflexion
Flexing the ankle so that the foot moves anteriorly in the sagittal plane
Plantarflexion
Extending the ankle so that the foot moves posteriorly in the sagittal plane
Pronation
Combined movements of abduction and eversion resulting in lowering of the medial margin of the foot
Supination
Combined movements of adduction and inversion resulting in raising of the medial margin of the foot
