Muscle Attachment Of Clavicle Flashcards
What is the primary function of the clavicle?
The clavicle serves as a strut that connects the arm to the body, stabilizing the shoulder.
Which muscles attach to the medial end of the clavicle?

True or False: The clavicle has an attachment site for the deltoid muscle.
True
Fill in the blank: The lateral end of the clavicle articulates with the _______ bone.
scapula
What muscle attaches at the acromial end of the clavicle?
The deltoid muscle attaches at the acromial end of the clavicle.
Name one muscle that originates from the clavicle.
The subclavius muscle originates from the clavicle.
Which ligament connects the clavicle to the first rib?
The costoclavicular ligament connects the clavicle to the first rib.
Multiple Choice: Which muscle does NOT attach to the clavicle? A) Sternocleidomastoid B) Pectoralis Major C) Biceps Brachii D) Trapezius
C) Biceps Brachii
What is the role of the trapezius muscle concerning the clavicle?
The trapezius muscle attaches to the lateral third of the clavicle and helps in the elevation and retraction of the scapula.
True or False: The clavicle is a flat bone.
True
Fill in the blank: The _______ muscle helps stabilize the clavicle during arm movements.
subclavius
What structure lies below the clavicle?
The subclavian artery and vein lie below the clavicle.
Which part of the clavicle is more commonly fractured?
The middle third of the clavicle is more commonly fractured.
Short Answer: What is the clinical significance of the clavicle in shoulder injuries?
The clavicle is often involved in shoulder injuries due to its position and role in connecting the arm to the trunk.
Which muscle is responsible for the depression of the clavicle?
The pectoralis minor muscle is responsible for the depression of the clavicle.
Multiple Choice: The conoid ligament is associated with which part of the clavicle? A) Medial end B) Lateral end C) Both D) None
B) Lateral end
True or False: The clavicle has a role in protecting the underlying neurovascular structures.
True
What is the anatomical term for the attachment site of muscles on the clavicle?
The anatomical term is ‘muscle origin and insertion points.’
Fill in the blank: The _______ ligament supports the acromioclavicular joint.
acromioclavicular
Which muscle acts to elevate the clavicle?
The sternocleidomastoid muscle acts to elevate the clavicle.
What is the effect of a fractured clavicle on shoulder mobility?
A fractured clavicle can lead to decreased shoulder mobility and pain.
What is the significance of the supraclavicular nerve in relation to the clavicle?
The supraclavicular nerve provides sensory innervation to the skin over the clavicle area.
Which muscle is primarily responsible for the protraction of the shoulder girdle?
The serratus anterior muscle is primarily responsible for the protraction of the shoulder girdle.
Fill in the blank: The _______ muscle aids in the stabilization of the clavicle during heavy lifting.
subclavius
What is the primary blood supply to the muscles attached to the clavicle?
The primary blood supply comes from the thoracoacromial artery and the subclavian artery.
