Muscles of the Anterior Neck

The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

Neck Exam

Source: Robert E. Sallis, MD. Kaiser Permanente, Fontana, California, USA Examination of the neck can be a challenge because of the many bones, joints, and ligaments that make up the underlying cervical spine. The cervical spine is composed of seven vertebrae stacked in gentle C-shaped curve. The anterior part of each vertebra is made up of the thick bony body, which is linked to the body above and below by intervertebral discs. These discs help provide stability and shock absorption to the...

Survivors of acute respiratory distress syndrome (ARDS) and critical illness frequently develop long-lasting muscle weakness. Manual muscle testing (MMT) is a standardized clinical examination commonly used to measure strength of peripheral skeletal muscle groups. This video demonstrates MMT using the 6-point Medical Research Council scale.

The effect of short-term resistance training on elderly people was investigated through the simultaneous use of several methods. Compared to a control group, many improvements were seen, including on muscle aerobic capacity, glucose tolerance, strength, power, and muscle quality (i.e., protein involved in cell signaling and muscle fiber type composition).

FAQs
Coordinated neural activation determines how effectively the cervical muscles produce force. The nervous system recruits motor units, and their combined activity enables the neck to work against resistance or hold the head in a prescribed position. This mechanism matters because a measured result reflects not only muscle tissue, but also the quality of motor control supporting posture and movement.
Motor-unit recruitment links brain-driven activation to observable neck performance. When motor units contribute in a coordinated way, the muscles can generate or sustain force during a task. In psychology studies, this link helps researchers treat neck strength as an objective motor measure rather than relying only on a participant’s report of discomfort, effort, or bodily experience.
A task requiring force against external resistance emphasizes active force production, whereas holding the head in a set position emphasizes sustained control. These demands may reveal different aspects of cervical performance because generating force and maintaining force are not identical task requirements. Identifying the condition used helps researchers interpret the resulting measure more precisely.
Assessment can be organized around two source-supported task formats: working against external resistance or maintaining the head in a set position. The researcher can therefore examine force production and sustained control as related but distinct aspects of performance. Keeping the task condition clear is important when interpreting what a recorded result represents.
Within psychology, the measure can complement investigations of posture, sensorimotor control, physical discomfort, and behavior. It provides an objective indicator of motor performance that can be considered alongside perception, attention, and reported experience. This combination helps researchers examine how measurable bodily function relates to psychological processes without treating either source of information as sufficient alone.
Reliable measurements can help distinguish observable motor performance from the psychological experience associated with it. A study may consider neck strength alongside discomfort, attention, perception, or behavior rather than using any one measure in isolation. This comparison can clarify how cervical motor function relates to everyday psychological experience and sensorimotor control.
