What else can I help you with?
The shoulder girdle is responsible for which movements of the scapula?
The shoulder girdle is responsible for movements such as protraction, retraction, elevation, depression, and upward and downward rotation of the scapula.
What is the strongest protractor of the scapula?
The strongest protractor of the scapula is the serratus anterior muscle. It originates from the upper ribs and inserts along the medial border of the scapula. Contraction of the serratus anterior muscle pulls the scapula forward around the rib cage.
When the superior iliac crest of the pelvis moves forward and downward from the normal anatomical position it is know as?
When the superior iliac crest of the pelvis moves forward and downward from the normal anatomical position, it is known as an anterior pelvic tilt. This can lead to changes in posture and alignment of the spine, potentially causing lower back pain or discomfort. Exercises focusing on core strengthening and stretching can help address this issue.
IS upward rotation of the scapula the same as lateral rotation?
No, upward rotation of the scapula refers to movement where the scapula moves upward and rotates in an upward direction around the axis. Lateral rotation, on the other hand, is the rotation of a bone around its longitudinal axis. These are two different types of movements.
A flat thoracic muscle deep to the pectoralis major that acts to draw the scapula inferiorly or to elevate the rib cage?
The muscle described is likely the serratus anterior. It originates on the surface of the upper ribs and inserts along the scapula. Its primary functions include protraction of the scapula (bringing it forward around the ribcage) and upward rotation of the scapula.
Which muscle moves the scapula forward?
Serratus Anterior, moves scapula forward.
What muscle moves the scapulae forward and rotate scapula upward?
The Serratus Anterior moves the scapula forward and rotates it upward.
What muscle raises ribs in forceful inhalation or pulls scapula forward and downward?
Rhomboid Major
What is the action of the serratus anterior?
Abducts scapula (moves scapula away from spinal column)
What is the action of the serratus anterior muscle?
Abducts scapula (moves scapula away from spinal column)
The shoulder girdle is responsible for which movements of the scapula?
The shoulder girdle is responsible for movements such as protraction, retraction, elevation, depression, and upward and downward rotation of the scapula.
What does the trapezius move?
Scapula, and the Lateral 3rd of the Clavicle.
What is the movement of the scapula when the humerus abducts?
Moves shoulder away
What structure does the scapula move upon?
The scapula moves against the posterior aspect of the rib cage. There is also articulation of the scapula with the humerous at the glenoid fosa and with the clavical at the acromion.
What moves food downward with no digestion?
The esophagus moves food downward without performing any digestive functions.
Do the pectorialis major and pectoralis minor produce different movement?
Yes, the pectoralis major is responsible for movements like arm flexion and horizontal adduction of the shoulder. In contrast, the pectoralis minor is involved in stabilizing the scapula by drawing it forward and downward.
What is the strongest protractor of the scapula?
The strongest protractor of the scapula is the serratus anterior muscle. It originates from the upper ribs and inserts along the medial border of the scapula. Contraction of the serratus anterior muscle pulls the scapula forward around the rib cage.
