Neck Muscles With Actions And Labels Youtube Muscles of the neck (musculi cervicales) the muscles of the neck are muscles that cover the area of the neck. these muscles are mainly responsible for the movement of the head in all directions. they consist of 3 main groups of muscles: anterior, lateral and posterior groups, based on their position in the neck. This video primarily focuses on flexors and extensors but also mentions muscles located on the neck, including some of the infrahyoids and levator scapulae .
The Cranial Nerve Exam Anatomy And Physiology The muscles of the neck are present in four main groups. the suboccipital muscles act to rotate the head and extend the neck. rectus capitis posterior major and rectus capitis posterior minor attach the inferior nuchal line of the occiput to the c2 and c1 vertebrae respectively. obliquus capitis superior also extends from the occiput to c1. Superficial muscles of the neck include: sternocleidomastoid (scm): a long, slender muscle that travels from the breastbone (sternum) to the collarbone (clavicle) and then on a diagonal up to the base of the skull. this muscle side bends, rotates, and bends the neck forward. scalenes (anterior, middle, and posterior): a group of three muscles. In addition, both muscles working together are the flexors of the head. place your fingers on both sides of the neck and turn your head to the left and to the right. you will feel the movement originate there. this muscle divides the neck into anterior and posterior triangles when viewed from the side (figure 11.4.8). The motion of the muscles of the neck are divided into four categories: rotation, lateral flexion, flexion, and hyperextension. rotation describes the action of moving the head from side to side.

The motion of the muscles of the neck are divided into four categories: rotation, lateral flexion, flexion, and hyperextension. rotation describes the action of moving the head from side to side. Common conditions that affect the neck muscles include: spasms: also called muscle cramps, muscle spasms occur when a muscle contracts and can’t relax. most spasms are short, lasting only a few seconds. but you may have a sore or stiff neck afterwards. strains: a neck strain is an injury to a muscle or tendon. The neck muscles, including the sternocleidomastoid and the trapezius, are responsible for the gross motor movement in the muscular system of the head and neck. they move the head in every direction, pulling the skull and jaw towards the shoulders, spine, and scapula. working in pairs on the left and right sides of the body, these muscles.
