2023年11月14日 · The following are muscles that either originate or insert (at least partially), or both, onto the vertebrae in the cervical spine. If a muscle attaches to the skull it will move the head, if it does not, the muscle will only move the neck.

An understanding of this anatomy is essential for assessment and treatment of cervical spine problems. The cervical spine’s major functions include supporting and cushioning loads to the head/neck while allowing for rotation, and protecting the spinal cord extending from the brain.

Your cervical spine is the neck region of your spinal column or backbone. It consists of your first seven bones (C1-C7). Other structures in or around your cervical spine are your intervertebral disks, spinal cord and nerves, muscles, tendons and ligaments.

2023年10月30日 · The platysma is a sheet-like muscle that lies within the subcutaneous tissue of the anterior neck, superficial to the investing layer of deep cervical fascia. It originates from the skin and fascia overlying the region of the clavicle and passes superiorly along the neck.

This overview article discusses the cervical spine’s anatomy and function, including movements, vertebrae, discs, muscles, ligaments, spinal nerves, and the spinal cord.

2024年2月8日 · What is the cervical spine? The cervical spine, or neck region of the spine, is made up of seven vertebrae, which are stacked bones. Your cervical spine’s first two vertebrae are distinct in both form and function. The atlas, or first vertebra (C1), is a ring-shaped bone that starts at the base of your skull.

In the cervical spine, the erector spinae muscles play key roles in supporting posture, rotating the neck, and extending the neck backward. The suboccipital muscles are 4 pairs of small muscles that connect the top of the cervical spine with the base of the skull. The suboccipitals are needed for head extension and rotation.

2023年8月28日 · To reach the cervical spine, skin and platysma muscle are first dissected, then sternocleidomastoid muscle, carotid sheath, and its content and other vital structures are identified and protected first.

2025年1月15日 · Spinous Processes: Short and often bifid (split into two prongs) in vertebrae C2 to C6, providing attachment points for muscles and ligaments. Transverse Processes: Contain transverse foramina, which house the vertebral arteries and veins that supply blood to the brain.

Here are some of the key muscles attached to the cervical spine: Levator scapulae. The levator scapulae muscle is attached at the top four cervical vertebrae (C1 to C4) and runs down the side of the neck to attach at the top of the shoulder blade (scapula).

The cervical spine (neck) starts at the base of skull and extends down to the thoracic spine. The neck joins head with trunk and limbs and it works as a major conduit for structures between them. Flexibility of neck movement allows and maximise necessary positions for head functions and its sensory organs.

The posterior scalene also originates from the cervical spine but attaches instead to the second rib. Together, the scalenes act to flex the neck. They can also be recruited as accessory muscles of respiration. These muscles are innervated by the posterior rami of …

2019年7月9日 · An expert understanding of cervical anatomy is critical to a spine surgeon operating in this region. An understanding of this anatomy is essential for surgical technique and diagnosis of pathologic processes. This chapter is a review of cervical spine osteology, ligaments, muscles, and neurovascular structures. Important Points

Ligaments hold the vertebrae in place, and tendons attach the muscles to the spinal column. The cervical spine is subjected to a range of extrinsic factors such as repetitive movements, whole-body vibrations and static load.[3]

2024年9月5日 · The first cervical vertebrae (C1) is known as the atlas. The second cervical vertebrae (C2) is known as the axis. In this article, we shall look at the anatomy of the cervical vertebrae – their characteristic features, articulations and clinical relevance.

Knowing the main parts of your neck and how these parts work is important as you learn to care for your neck problem. Two common anatomic terms are useful as they relate to the neck. The term anterior refers to the front of the neck. The term posterior refers to the back of the neck.

2025年1月15日 · Structure and Anatomy Vertebral Segments. The spine is composed of 33 vertebrae, categorized into five regions: Cervical Spine (7 Vertebrae): Labeled C1 to C7, located in the neck, ... Attachment for Muscles and Ligaments The spine provides numerous attachment points for muscles and ligaments, which facilitate movement, maintain posture, and ...

2022年5月24日 · Find out about the cervical vertebrae - definition, numbers of neck bones in humans, with anatomy, parts, functions, and labeled pictures.

2018年1月19日 · Several muscles support the vertebrae of the spine. The spinalis moves the spine and helps maintain correct posture. It is divided into three parts: Spinalis cervicis: This muscle begins in the...

Doctors often refer to these verte- brae as C1 to C7. The cervical spine starts where the top vertebra (C1) connects to the bottom of the skull. The cervical spine curves slightly inward and ends where C7 joins the top of the thoracic spine (the chest area). This guide gives a general overview of the anatomy of the neck. It should help.

The cervical spine, which consists of the first seven vertebrae in the neck, plays a crucial role in supporting the head and facilitating movement. Recent studies have focused on the myodural ...

Deep Cervical Fascia: Comprising three sub-layers, this fascia supports critical neck structures: Investing Layer: The sternocleidomastoid and trapezius muscles are surrounded by the investing layer, which offers structural support. Prevertebral Fascia: Provides spinal stability by enveloping the cervical spine and related muscles.
