Muscles of neck Neck muscles are bodies of tissue that produce motion in the neck when stimulated. The muscles of the neck run from the base of the skull to the upper back and work together to bend the head and assist in breathing.The motion of the muscles of the neck are divided into four categories: rotation, lateral flexion, flexion, and hyperextension.eck muscles are bodies of tissue that produce motion in the neck when stimulated. The muscles of the neck run from the base of the skull to the upper back and work together to bend the head and assist in breathing.

- Primary Lab Objectives and Goals: Expose and identify the epaxial muscles (deep muscles that lie along the vertebral column). Understand that muscles act on the back and there are multiple layers (with different names) from deep to superifical. Expose the muscles and nerves of the suboccipital triangle (region of the posterior neck below the head).

Learn Muscle Anatomy: Muscles of Plantarflexion Triceps Surae. The triceps surae is a group of muscles in the posterior compartment of the distal leg, made up of the gastrocnemius, soleus, and their common tendon, the Achilles tendon; the triceps surae is commonly known as the calf.ne of the most common injuries is ankle sprains, specifically straining the anterior talofibular ligament (ATF). So, the next time you watch a ballet performance (or cringe your way through the movie Black Swan), think of all the muscles working together to lift those graceful dancers up onto their toes.

Scalene Muscles (2) The scalenus medius is similar to the scalenus anterior and raises the first rib from above or bends to slightly rotate ... Click to read more below. The scalene muscles are lateral vertebral muscles that begin at the first and second ribs and pass up into the sides of the neck. There are three of these muscles.(1) The scalenus anterior muscle, which, when the neck is fixed, elevates the first rib to aid in breathing; or when the rib is fixed, bends the neck forward and sideways and rotates it to the opposite side.hen the scalene muscles are fixed from above, they elevate the first and second ribs to become respiratory muscles for breathing. Acting from below, they bend the spinal column to the same side or, if muscles act on both sides, the spinal column is slightly flexed.

Structures and Spaces Structures and Spaces Below the skin in the lower neck is a thick layer of fatty tissue called the scalene fat pad, which helps to protect the deeper muscular and neurovascular structures of the thoracic outlet. The presence of the scalene fat pad also makes it difficult to feel the structures of the thoracic outlet when pressing with the fingers on the lower neck.

Scalene muscles Scalene muscles. The scalene muscles (from Greek σκαληνός, or skalenos, meaning uneven as the pairs are all of differing length) are a group of three pairs of muscles in the lateral neck, namely the anterior scalene, middle scalene, and posterior scalene. They are innervated by the fourth, fifth, and sixth cervical spinal nerves (C4-C6).

The Superficial Back Muscles The trapezius is a broad, flat and triangular muscle. The muscles on each side form a trapezoid shape. It is the most superficial of all the back muscles. 1  Attachments: Originates the skull, spinous processes of C7-T12 and the ligamentum nuchae.2  Innervation: Motor innervation is from the accessory nerve. 3  Actions: The upper fibres of the trapezius elevates the scapula and rotates it during abduction of the arm.he muscles on each side form a trapezoid shape.

Computer Neck Syndrome: Postural Causes of a Common Malady Both these groups are in the front of the body, the pecs being the chest muscles and the scalenes residing on the front of the neck. Tight pecs round the shoulders, while tight scalenes jut the chin forward—sort of Quasimodo-like, I always say.

Muscles of respiration In human physiology, the muscles of respiration are those muscles that contribute to inhalation and exhalation, by aiding in the expansion and contraction of the thoracic cavity.The diaphragm and, to a lesser extent, the intercostal muscles drive respiration during quiet breathing.Additional 'accessory muscles of respiration' are typically only used under conditions of high metabolic demand (e.g. exercise) or respiratory dysfunction (e.g. an asthma attack).he diaphragm and, to a lesser extent, the intercostal muscles drive respiration during quiet breathing.

List of Upper Body Muscles Chest. The chest region includes two muscle groups and one individual muscle. The muscle groups are the pectoralis major, which is made up of a clavicular and a sternal head, and the serratus anterior, which is made up of a superior and an inferior head.he shoulders comprise four different muscles, two of which are muscle groups. The individual muscles of the shoulders are the upper trapezius and the levator scapulae, which function to elevate the scapulae, or shoulder blades.

- The scalenes laterally flex the cervical spine and assist in elevating the rib cage while breathing. The scalene muscles, as a whole, can refer pain into the chest, into the lateral upper limb, the medial scapular border and interscapular area, as well as pain in the thumb and index finger of the affected side.

Scalene Muscles: Neck, Shoulder, Chest, Upper Back, Arm, Pain 1 In about 30% of the population, another scalene muscle, the scalenus minimus is found. The scalenus minimus is often only found on one side of those who have this ‘extra’ muscle.  The scalene muscles are seldom painful, yet refer pain throughout the chest, upper back, shoulders, arms and neck.

Interscalene Nerve Block Background. Interscalene nerve block refers to the technique of anesthetizing the roots or trunks of the brachial plexus in the neck between the anterior and middle scalene muscles.The procedure was first well described and popularized by Alon Winnie in 1970.pence et al compared the effectiveness of an injection between the middle scalene muscle and brachial plexus sheath (periplexus) with an injection within the brachial plexus sheath (intraplexus) in 170 patients. There was no difference between the 2 groups in block onset times or block quality.

Muscles of the Chest and Upper Back Muscles of the Chest and Upper Back. The muscles of the chest and upper back occupy the thoracic region of the body inferior to the neck and superior to the abdominal region and include the muscles of the shoulders.n addition to moving the arm and pectoral girdle, muscles of the chest and upper back work together as a group to support the vital process of breathing. The diaphragm is a strong, thin, dome-shaped muscle that spans the entire inferior border of the rib cage, separating the thoracic cavity from the abdominal cavity.
