Getting Familiar With Neck Muscle Anatomy

Anatomy neck muscle
The neck muscle anatomy is worth studying because of its function and the role it plays in our body. For the past centuries, there were many studies and researches that had been conducted to understand the human body. We are now blessed because of the immense body of knowledge accumulated pertaining to the anatomy of the neck muscles. It is therefore a must for us to explore more about this subject.

Overview of the Neck Muscle Anatomy

The neck is a broad term to describe the part of our body that directly supports the head. The neck muscle anatomy is composed of many structures, tissues, and nerves, and other anatomical body parts. But for this sake of discussion, we will just focus on the musculoskeletal system.

Muscles of the Neck and their Description

  • Infrahyoids - Anatomy neck muscle
    Infrahyoids – aids in pulling down the thyroid cartilage and hyoid bone; located near the hyoid bone and thyroid cartilage.
  • Suprahyoids - Neck muscle anatomy
    Suprahyoids – aids in elevating the tongue and hyoid bone; depresses the mandibular bone. It Functions during swallowing, chewing, and talking; located near the hyoid bone.
  • Splenius cervicis - Anatomy of the neck muscle
    Splenius cervicis – rotates and extends the neck; located near the transverse processes between C1-C4.
  • Splenius capitis - Muscle of the neck anatomy
    Splenius capitis – rotates and extends the neck; located between the superior nuchal of occiput and the temporal bone’s mastoid process.
  • Longissumus capitis - Neck muscle anatomy
    Longissumus capitis – flexion of the head; located at the inferior part of the occipital bone.
  • Scalenes - Anatomy neck muscle
    Scalenes (anterior, posterior, medius) – aids in respiration by elevating ribs during inhalation; flexes and rotates the neck. Delicate because of the subclavian artery and brachial plexus run through the anterior and middle scalene. The anterior and middle scalenes are located at the first rib while the posterior scalene is at the second rib.
  • Platysma - Anatomy of the neck muscle
    Platysma – depresses the mandibular bone and the lower lips; located at the inferior part of the face and at the edge of the mandibular bone.
  • Sternocleidomastoid - Muscle of the neck anatomy
    Sternocleidomastoid – flexion and rotation of the head and neck; located at the mastoid processes of the temporal bone.


Functions of the Neck Muscle Anatomy

Functions of the Neck Muscle Anatomy
The primary functions of the neck muscle anatomy are to support the head and to allow movement. The motion of the neck could be side-to-side, lateral flexion, flexion, and hyperextension. There are many muscles of the neck but all of them work together to efficiently control, coordinate, and support the movement of the neck.

Summary of the Neck Muscles

The message is clear; we cannot live without neck muscles. It is only therefore important that we understand and take care of our necks. Though there are many types of neck muscles, all of them work in a synergistic manner to come up with an efficient performance. The functions of the neck muscle anatomy are now better understood because of years and years of study and research of our founding fathers in the field of biology.

This article has given you the basic information that you need to know about the neck muscles. The neck muscle anatomy, as well as its physiology, is truly an amazing mechanism of the body.
