What is the origin insertion and action of sternocleidomastoid?

It is a ‘two headed’ muscle, meaning it has two origin sites and one insertion site. The SCM’s origins are the sternum and clavicle and its insertion is the mastoid process behind the ear. The actions of the SCM are to flex and rotate the head. It does this by contracting both SCMs together or one alone, respectively.

Muscle insertion refers to a muscle’s distal attachment—the end of the muscle furthest away from the torso. For example, the bicep insertion occurs at the elbow.

What is the Sternohyoid?

The sternohyoid is a strap like infrahyoid muscle that connects the hyoid bone with the clavicle and sternum. … The function of this muscle is to reestablish the breathing process by pulling the hyoid bone and larynx inferiorly after deglutition. This article will discuss the anatomy of the sternohyoid muscle.

Where does the orbicularis oculi attach laterally?

From the orbital margin, the muscle extends inward and inserts on the lateral palpebral raphe, which is a ligament that is located on the outer part of the eye socket. The orbicularis oculi muscle inserts onto the lateral palpebral raphe which is located on the outer part of each eye socket.

What is the inferior attachment insertion of the temporalis?

What is the inferior attachment/insertion of the temporalis? Temporal Fossa/Coronoid process and ramus of mandible.

What is the distal attachment of levator scapulae?

The levator scapulae originates from the posterior tubercle of the transverse process of cervical vertebrae one to four. The muscle is inserted into medial border of the scapula extending from superior angle to junction of spine and medial border of scapula.

Where is the rhomboid minor?

Rhomboid minor muscle is a muscle of the back and upper limb, which acts on the scapula.

Where is the rhomboid muscle?

The rhomboid muscles are a large group of muscles in your upper back. They’re made up of the rhomboid major and the rhomboid minor. These and other muscles form the shoulder girdle that holds your shoulder blade and shoulder stable.

Which of the following bones is not connected to the Sternocleidomastoid?

What is the only extrinsic eye muscle to originate from the anterior orbit? … Which of the following bones is NOT attached to the sternocleidomastoid muscle? Mandible. What is the largest and most powerful muscle of the erector spinae muscle group?

Where is the Triangularis?

Muscles of the head, face, and neck (labeled as triangularis near chin). The depressor anguli oris muscle (triangularis muscle) is a facial muscle. It originates from the mandible and inserts into the angle of the mouth. It is associated with frowning, as it depresses the corner of the mouth.

What does the Platysma muscle connect to?

The platysma muscle is a muscle that begins at the upper chest/shoulder areas and extends upward through the sides of the neck and attaches to the skin around the mouth and mandible. In the neck, this muscle covers the sternocleidomastoid, which is a deep muscle that runs up vertically on each side of the neck.

Are jaw muscles connected to the neck?

Because muscles in your neck are connected to your jaw, muscle tension that starts in your TMJ can move to your neck. This causes aches, spasms, tension and reduced flexibility in your neck.

Where does the lower trapezius insertion?

They found that the lower trapezius originates on the spine and extends from T2 to T12 and inserts onto the spine of the scapula from the acromian process to its root. It is closely aligned to the middle trapezius which attaches to the C7 and T1 vertebrae, and this also attaches to the spine of the scapula.

What muscle connects your neck and shoulder?

The levator scapulae muscle attaches to the top four cervical vertebrae and runs down the side of the neck to where it connects with the top of the shoulder blade. This muscle helps with lifting the shoulder blade, bending the neck to the side, and rotating the head.

What is the distal attachment of the trapezius?

It attaches distally onto the spine of the scapula, acromion, and distal third of the clavicle. Detailed morphometric measurements have been performed on this muscle (Kamibayashi & Richmond, 1998). Because of its size and the many locations of its attachments, the trapezius muscle also has many actions.
