What else can I help you with?
Which muscle will depress the scapula or elevate the ribs?
The pectoralis minor originates on the third to the fifth ribs (and elevates ribs). It depresses the scapula (and elevates ribs).
Which muscle acts as a synergist with pectoralis minor during abduction of scapula?
The serratus anterior muscle acts as a synergist with the pectoralis minor during abduction of the scapula. These two muscles work together to provide stability and control movement of the scapula during activities like raising your arms overhead.
Moves the scapula forward and downward?
The primary muscle responsible for moving the scapula forward and downward is the serratus anterior. This muscle originates along the upper eight or nine ribs and inserts along the inner border of the scapula. Contraction of the serratus anterior pulls the scapula forward and downward along the ribcage.
What is pectoralis epicoracoidea?
Muscles in the pectoral region of a frog. It opposite of dorsalis scapula by: Adrenocorticotropic hormone and Adenosine Tri Phospate with anti deuretic hormone and nicotinamide adenine dinucleotide phospate hydrogen and also rectus femoris anticus and horizontal skeletogenious septum
Does the trapezius contract?
Trapezius muscle- located from the skull through the cervical and thoracic vertebrae to the lateral 1/3 of the clavicle and spine of scapula. Function: Elevates, Depresses, Retracts, and rotates the scapula up and down. Innervated by the Spinal Accessory Nerve
What flat thoraic muscle deep to the pectoralis major that acts to draw the scapula inferiorly or to elevate the rib cage?
External intercostals
Which muscle will depress the scapula or elevate the ribs?
The pectoralis minor originates on the third to the fifth ribs (and elevates ribs). It depresses the scapula (and elevates ribs).
Which of the muscles pull the scapula into a down?
Pectoralis Minor
Which shoulder joint muscles do not attach on the scapula?
Pectoralis Major
Are the thoracic vertebrae medial or lateral to the scapula?
You can describe them as medial to the scapula.
Which muscle acts as a synergist with pectoralis minor during abduction of scapula?
The serratus anterior muscle acts as a synergist with the pectoralis minor during abduction of the scapula. These two muscles work together to provide stability and control movement of the scapula during activities like raising your arms overhead.
What muscles is the prime mover to protract scapula?
By protraction, I assume that you mean shifting (rotating) the shoulder girdle anteriorly, which involves moving the scalula away from the spine (such as is requires when reaching forward). This motion requires movement at the sternoclavicular, acromioclavicular, and coracoclavicular joints, and is performed by actions of the serratus anterior, pectoralis minor and pectoralis major.The opposite movement, retraction, is backward movement of the shoulder girdle, and involves moving the scapula back toward the spine. Trapezius (middle and lower fibers), rhomboids and latissimus dorsiare responsible for retraction.
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 muscle attaches to the vertebral border of the scapula?
Muscles that attach to the scapula are:The Pectoralis minor.The coracobrachialis.The short head of biceps brachii.
Which muscle protracts and depresses the scapula?
The serratus anterior muscle protracts and depresses the scapula. It originates on the upper ribs and inserts along the medial border of the scapula. This muscle is important for stabilizing the scapula during movements like pushing and reaching overhead.
Do the pectoralis major and pectoralis minor produce different movements?
Yes, the pectoralis major is responsible for movements like shoulder flexion, adduction, and medial rotation, while the pectoralis minor assists in stabilizing the scapula by depressing and protracting it. They work together to facilitate various arm and shoulder movements.
Moves the scapula forward and downward?
The primary muscle responsible for moving the scapula forward and downward is the serratus anterior. This muscle originates along the upper eight or nine ribs and inserts along the inner border of the scapula. Contraction of the serratus anterior pulls the scapula forward and downward along the ribcage.
