The neck is a complex region of the body, with a dozen or so muscles that support and move the head and neck. These muscles are essential for keeping the head balanced and stable, and they also help protect the neck from injury. Neck muscle injuries can be painful and cause stiffness, headaches, and even numbness or tingling sensations in the shoulders and arms. Therefore, it is important to keep the neck muscles healthy and strong through training and exercise. By understanding the different muscles in the neck and their functions, we can better care for our necks and improve our overall well-being.

What You'll Learn
There are about 20 neck muscles
The neck is a complex region of the body, with about 20 muscles that support and move the head and neck. These muscles are some of the smallest in the human body, but they play a significant role in keeping the head and neck stable and balanced.
The neck muscles can be broadly categorised into four groups: the anterior, lateral, and posterior muscles, as well as the superficial neck muscles. The anterior neck muscles include the superficial, suprahyoid, infrahyoid, and prevertebral muscles. The suprahyoid muscles, such as the mylohyoid and geniohyoid, control the hyoid bone during movements like swallowing and speaking. The infrahyoid muscles, such as the sternohyoid and omohyoid, are involved in depressing the hyoid bone and the larynx. The prevertebral muscles, such as the longus colli and longus capitis, are the deepest muscles of the anterior group, situated anterior to the spine.
The lateral neck muscles include the scalene muscles, with three paired muscles: the anterior, middle, and posterior scalene. These muscles help with neck rotation and pulling the head back. The posterior neck muscles are grouped into three categories: the superficial muscles, which help with lateral and bilateral neck bending; the suboccipital muscles, which assist in head rotation and neck bending; and the transversospinalis muscles, which extend the head, cervical spine, and thoracic spine, while also contributing to spine stability.
It is important to keep the neck muscles healthy as they are susceptible to injuries and conditions like whiplash, pinched nerves, and muscle strains from poor posture or overuse. Training the neck muscles can help prevent injuries and improve athletic performance.

They support the head and neck
The neck is a complex region of the body, with about a dozen muscles that support the head and neck. These muscles are crucial for keeping the head stable and balanced, allowing it to move in multiple directions. They also help protect the neck from injury and keep the spine aligned.
The neck muscles can be divided into four main categories: anterior, lateral, posterior, and deep cervical muscles. The anterior neck muscles, such as the superficial neck muscles and the suprahyoid muscles, help with movements of the lower face, mouth, and front of the neck. They also enable you to angle your neck downward and rotate it. The infrahyoid muscles, located below the hyoid bone, work to depress it, while the anterior vertebral muscles are the deepest muscles of the anterior group, situated anterior to the spine.
The lateral neck muscles consist of five muscles that aid in head movement and neck contraction. The posterior neck muscles are grouped into three categories: superficial muscles, which help with lateral and bilateral neck bending; suboccipital muscles, which enable head rotation and neck bending; and transversospinalis muscles, which extend and bend the head, neck, and spine in various directions, also providing support and stability to the spine.
The deep cervical muscles, a group of small muscles running from the skull to the upper back, are essential for head and neck stabilisation. They also play a protective role for the spine. One of the main muscle groups involved in stabilisation is the trapezius, a large, triangular muscle extending from the skull to the lower back.

They enable head movement
The neck is home to about a dozen muscles, some of the smallest in the human body. These muscles play a significant role in supporting and enabling head movement. Neck muscles ensure the head remains balanced and can move in multiple directions. All 20 neck muscles help keep the head safe and stable.
The front neck muscles consist of superficial neck muscles, which help move the mouth, lower face, and front of the neck. They also help angle the neck downward and rotate the neck. The suprahyoid muscles move the jaw and control the hyoid bone during swallowing or speaking. The infrahyoid muscles move the hyoid bone and larynx down. The scalenes are another muscle in the anterior neck that helps rotate the neck and pull the head back.
The lateral neck muscles play a role in moving the head around and contracting the neck. The posterior neck muscles help bend the neck laterally and bilaterally, rotate the head, and bend the head, neck, and spine in different directions. They also help support and stabilize the spine.
It is important to keep the neck muscles healthy to reduce the risk of injury and increase mobility and performance. Training the neck muscles can help prevent injuries and improve athletic performance.

Neck injuries are common
The neck is a complex region of the body, with about 20 muscles that support the head and neck and allow for a wide range of motion. These muscles are crucial for maintaining head stability and balance, and any injuries to them can have significant impacts on daily life.
Neck injuries are indeed common, with neck pain being a widespread issue. This pain can be acute, lasting from days to six weeks, or chronic, persisting for more than three months. The most common cause of neck problems is whiplash, often resulting from automobile accidents. However, there are other factors that can lead to neck injuries and pain.
Repetitive neck movements, such as those in certain jobs or sports, can strain the neck muscles and cause pain. Spending too much time bent over laptops, smartphones, or books can also cause muscle strains and impact posture, leading to neck pain. Additionally, trauma or injury to the neck can occur through accidents, sports, or even sleeping in the wrong position.
Other causes of neck pain include genetic factors, such as a family history of neck pain or neck arthritis, and various health conditions. These conditions can include meningitis, rheumatoid arthritis, cancer, infections, and rheumatological conditions. Moreover, growths like tumors, cysts, or bone spurs can put pressure on the nerves in the neck, resulting in pain.
It is important to address neck injuries and pain promptly. Treatment options include pain medications, muscle relaxants, physical therapy, injections, and acupuncture. Physical therapy, in particular, can help improve flexibility and strengthen neck muscles, reducing the risk of future injuries.

Training them is important
The neck is one of the most complex regions of the body, with about a dozen muscles. These muscles are responsible for supporting the head and neck and enabling movement in multiple directions. The neck muscles can be categorised into four main groups: lateral, anterior, posterior, and those that stabilise the head.
Training these neck muscles is important, and here's why:
Injury Prevention
A well-conditioned neck is more resilient to sudden impact injuries, such as those from sports or vehicular accidents. A strong neck can also help absorb shocks, protecting the spine and reducing the risk of spine accidents. This is especially important for athletes and those who sit at a desk all day, as they are more prone to neck injuries.
Improved Performance
A strong neck improves athletic performance and enhances physical health. It serves as a foundation for upper-body strength and stability, facilitating optimal performance in various exercises. A robust neck also improves mobility and flexibility, increasing the range of motion.
Aesthetics
A thick and muscular neck is often associated with strength and power and is considered aesthetically pleasing by many.
Posture and Pain Reduction
Training your neck muscles can help improve posture and reduce neck and back pain. It helps to release tension and stiffness in the neck and surrounding areas, improving overall physical health and well-being.
Brain-Body Connection
Neck training can improve the signals from the brain to the body, enhancing breathing and overall performance.
It is important to note that neck training should be avoided by those with a history of neck pain, injury, or instability, as well as those with neurological conditions. For those starting a neck training regimen, it is crucial to begin slowly and gradually increase the intensity and frequency of workouts. Additionally, consulting a medical professional is always recommended before embarking on any new training program.
