Sauropod neck posture is a subject occasionally debated among scientists, with some favoring postures closer to horizontal whilst others a more upright posture. Research has looked at various avenues of evidence and analysis including: attempting to reconstruct the neutral posture of their necks and estimating range of motion by studying the ...
In medicine and occupations concerned with physical fitness, the concept of good posture is referred to as "neutral spine". [7] In this context, proper posture or "neutral spine", is the proper alignment of the body between postural extremes. Deviations from neutral alignment are identified as excessive curvature or reduction in curvature.
The triangles of the neck describe the divisions created by the major muscles in the region.. The side of the neck presents a somewhat quadrilateral outline, limited, above, by the lower border of the body of the mandible, and an imaginary line extending from the angle of the mandible to the mastoid process; below, by the upper border of the clavicle; in front, by the middle line of the neck ...
The muscles of the neck, which are separate from the compartments, form the boundaries of the neck triangles. [2] In anatomy, the neck is also referred to as the cervix or collum. However, when the term cervix is used alone, it often refers to the uterine cervix, the neck of the uterus. [3]
It promotes stabilization of head position by innervating the neck muscles, which helps with head coordination and eye movement. Its function is similar to that of the tectospinal tract . The lateral vestibulospinal tract provides excitatory signals to interneurons , which relay the signal to the motor neurons in antigravity muscles. [ 6 ]
Acute calcific tendinitis of the longus colli muscle can occur. This presents with acute onset of neck pain, stiffness, dysphagia and odynophagia, and must be distinguished from retropharyngeal abscess and other sinister conditions. Imaging diagnosis is by CT or MRI, demonstrating calcification in the muscle in addition to retropharyngeal oedema.
The anterior longitudinal ligament is a ligament that extends across the anterior/ventral aspect of the vertebral bodies and intervertebral discs the spine. It may be partially cut to treat certain abnormal curvatures in the vertebral column, such as kyphosis.
Torticollis can also be caused by problems with bones, muscles, or the spine in the neck, leading to difficulty moving the head and neck normally. [25] Knowing about the sternocleidomastoid muscle and how it works is crucial for doctors to diagnose and treat torticollis correctly, so they can find and fix the problem causing it.
