Term

Abduct/Protract scapula?

[image]

i.e. Forward movement away the midline of the body; moving the scapula away from the spine during prostration of the shoulder girdle.

Definition

Serratus anterior

Pectoralis minor

Term

Adduct/Retract scapula?

[image]

i.e. Backward movement toward the midline of the body; moving the scapula back toward the spine during retraction of the shoulder girdle.

Definition
  • Trapezius
  • Rhomboids
Term

Upward Rotation of scapula?

[image]

i.e. Rotary movement of the scapula; moving inferior angle of scapula laterally and upward.

Definition
  • Trapezius
  • Serratus anterior 
Term

Elevation of scapula?

[image]

i.e. Superior movement of the shoulder girdle; moving the scapula up.

Definition
  • Trapezius
  • Levator scapulae
Term

Depression of scapula?

[image]

i.e. Inferior movement of the shoulder girdle; moving the scapula down.

Definition

Pectoralis minor

Latissimus dorsi

Trapezius

Term

Downward Rotation of scapula?

[image]

i.e. Rotary movement of the scapula; moving inferior angle of scapula medially and downward.

Definition
  • Levator scapulae
  • Rhomboids
  • Pectoralis minor
Term

Flexion of arm?

[image]

i.e. Bending the joint resulting in a decrease of angle; moving the upper arm upward to the front.

Definition
  • Deltoid
  • Pectoralis major
Term

Extension of arm?

[image]

i.e.Straightening the joint resulting in an increase of angle; moving the upper arm down to the rear.

Definition
  • Latissimus dorsi
  • Deltoid
  • Pectoralis major
  • Teres major
Term

Abduction of arm?

[image]

Lateral movement away from the midline of the body; moving the upper arm up to the side away from the body.

 

Definition
  • Deltoid
  • Supraspinatus (initiates it)
Term

Medial Rotation of arm?

[image]

Rotary movement around the longitudinal axis of the bone toward the center of the body; turning the upper arm inward. See shoulder internal rotation inflexibility.

Definition
  • Pectoralis major
  • Latissimus dorsi
  • Deltoid (anterior)
  • Subscapularis
  • Teres major
Term

Lateral Rotation of arm?

[image]

Rotary movement around the longitudinal axis of the bone away from the center of the body; turning the upper arm outward. See shoulder external rotation inflexibility.

Definition
  • Teres minor
  • Infraspinatus
  • Deltoid
Term

Adduction of arm?

[image]

Medial movement toward the midline of the body; moving the upper arm down to the side toward the body.

Definition
  • Latissimus dorsi
  • Teres major
  • Pectoralis major
Term

Flexion of spine? What prevents hyperflexion?

[image]

Bending the joint resulting in a decrease of angle; moving the spine Forward; the neck moves toward the chest.

Definition

Sternocleidomastoid

 

The posterior longitudinal ligament attaches to the IV discs and borders of the bodies. It runs with the vertebral canal, and prevents hyperflexion.

Term

Extension of spine? What prevents hyperextension?

[image]

Straightening the joint resulting in an increase of angle; moving the spine back; the neck moves away from the chest.

Definition
  • Splenius capitus
  • Semispinalis capitis
  • Semispinalis cervicis
  • Erector spinae
    • Iliocostalis
    • Longissimus

Anterior ligament attaches to the anterior surfaces of the bodies and discs and prevents hyperextension.

Term

Extension of neck?

[image]

Straightening the joint resulting in an increase of angle; moving the head backward at the joint just below the skull.

Definition
  • Semispinalis capitis
  • Splenus capitis
  • Rectus capitis posterior major
  • Rectus capitis posterior minor
  • Obliquus capitis superior
  • Longissimus capitis
Term

Abduction, Adduction, and Rotation of neck?

[image]

Lateral movement away from the midline of the body; moving the head toward the shoulder (left or right) at a joint below the skull.
Return to the anatomical position from lateral movement; moving the head upright away from the shoulder at a joint below the skull.
Rotary movement around the longitudinal axis of the bone; turning the head to the side (right or left) at a joint below the skull.
Definition
  • Sternocleidomastoid
  • Obliquus capitis inferior
  • Obliquus capitis superior
  • Rectus capitis lateralis
  • Longissimus capitis
  • Splenius capitis
  • Term

    Abduction/Adduction/Rotation of Spine?

    [image]

    Ad (shown above): Lateral movement away from the midline of the body; moving the spine to the side (left or right); the neck moves toward the shoulder.

    Ab: Return to the anatomical position from lateral movement; straightening the neck from lateral flexion.

    Rotation: Rotary movement around the longitudinal axis of the bone; turning the spine to the side (right or left); the neck turns toward the shoulder.
