What is the origin and insertion of the Platysma

The platysma originates from the fascia that covers the clavicle, the acromial region and the superior portions of the pectoralis major and deltoid muscles. … The platysma has several insertion points. Its medial fibers insert onto the lower border of the mandible or the skin of the lower lip.

What is the origin of the platysma?

The platysma, innervated by the facial nerve, is a thin, sheet-like voluntary muscle. Origin: the muscle has a broad origin with fibers arising from the fascia of the upper thorax including the clavicle, acromial region, pectoralis major and deltoid muscles.

What does the platysma muscle connect to?

Since the platysma muscle attaches to the bone and skin around the lower jawbone (also known as the mandible), the action of this muscle mostly pertains to this area of the body. The specific actions of the platysma muscle include: Pulling the corner of the lips out to the side and down, and.

Where is the platysma muscle located?

Dissimilar to other muscles of the body that lie deep to the subcutaneous tissue, the platysma is located within the subcutaneous tissue of the neck (superficial layer of the cervical fascia). Its superficial position means that surgical dissections of the neck must acknowledge the underlying neurovascular structures.

What is the Sternocleidomastoid origin?

Origin and insertion The sternal head originates from the manubrium sterni, while the clavicular head from the medial third of the clavicle. The insertion is the lateral surface of the mastoid process of the temporal bone and the lateral half of the superior nuchal line of the occipital bone.

What is the origin insertion and action of the masseter?

The masseter is one of the muscles of mastication. It is a powerful superficial quadrangular muscle originating from the zygomatic arch and inserts along the angle and lateral surface of the mandibular ramus. The masseter is primarily responsible for the elevation of the mandible and some protraction of the mandible.

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 are platysma bands?

The platysmal bands are the two muscles that are located on both sides of your neck. Since the neck has a much thinner layer of skin than the face and the skin around your neck naturally loses fat deposits and collagen as you get older, these muscles usually become increasingly visible over time.

What is a platysma muscle lift?

A platysmaplasty is named for the platysma muscles which run along the front of the neck. The surgery tightens the skin and underlying muscles to lift the neck. 1 It also improves and sharpens the contour of the jawline.

Why do Platysmal bands separate?

Platysma are a thin, broad sheet of muscles, positioned on each side of the neck. It is divided into two separate and distinct sides, which meet in the center. As these muscles become weaker and separate, the unwanted platysma bands develop.

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.

What is the insertion of the trapezius muscle?

Insertion. The muscle inserts on the lateral third of clavicle, acromion, and spine of scapula.

What is the origin of the masseter muscle exercise 11?

The origin of the masseter muscle is the zygomatic arch. The zygomatic arch, also called the cheek bone or zygomatic process, is a bony arch that connects the temporal and zygomatic bones, which are located on the sides of the face/skull.

What is the origin and insertion of the Buccinator muscle?

Origin and insertion Its superior part arises from the outer surface of the alveolar process of the maxilla opposite to the three maxillary molar teeth. The inferior part also arises from the alveolar part of the mandible opposite to the three mandibular molar teeth.

What is the origin of a muscle?

Muscle origin is a term referring to one end of a muscle, generally at the location where it attaches to a bone. The main part of the muscle called the belly of the muscle, then crosses over the gap between this bone and another usually adjacent bone — to attach there.

Use your tongue to help strengthen your platysma muscle. Sit up straight and open your mouth as far as you can, without discomfort. Stick your tongue out, then reach it down toward your chin. Hold for three to five seconds, then relax.

What are neck bands?

Neck bands, also known as necklines or necklace lines, are horizontal lines which traverse the front of the neck. Sometimes, they are more noticeable than wrinkles in the face due to the relative lack of fat in the neck area. Neck bands are generally a result of natural aging, but they can be prominent in young people.

What age do neck bands start?

These indented wrinkles have the appearance of circular rings that create horizontal creases across the neck and look as if you have tight, invisible, indented cords around your neck. It is not uncommon for these stubborn and unattractive lines to begin as early as your 20’s and progress with age.

Is the Platysma a muscle of mastication?

-Superficial to the muscle are the integument, the Platysma, the Risorius, the Zygomaticus major, and the parotid gland; the parotid duct, branches of the facial nerve, and the transverse facial vessels cross the muscle. …

What is Platysmal plication?

A “turkey” neck is the outcome of both the aging process and the separation and thickening of a thin neck muscle known as the platysma. To correct this irregularity, a small incision is made in the neck.

What is SMAS in plastic surgery?

The SMAS (superficial muscular aponeurotic system) is a layer of tissue deep within the skin and subcutaneous tissue. It is one of the most important support structures for the face. The manipulation of this anatomic structure changes the appearance of the face.

What is submental lipectomy?

A neck lift, also known as a submental lipectomy, is a surgical procedure that removes localized fat deposits under the chin, corrects muscle laxity, tightens sagging skin or enhances a receding chin.

What is turkey neck?
