Striated muscle tissue is a muscle tissue that features repeating functional units called sarcomeres. The presence of sarcomeres manifests as a series of bands visible along the muscle fibers, which is responsible for the striated appearance observed in microscopic images of this tissue. There are two types of striated muscle:
The infrahyoid muscles, or strap muscles, are a group of four pairs of muscles in the anterior (frontal) part of the neck. [1] The four infrahyoid muscles are the sternohyoid, sternothyroid, thyrohyoid and omohyoid muscles. [1] Excluding the sternothyroid, the infrahyoid muscles either originate from or insert on to the hyoid bone. [2]
It is a layer of striated muscle deep to the panniculus adiposus. [1] In humans, the platysma muscle of the neck, palmaris brevis in the hand, and the dartos muscle in the scrotum are described as a discrete muscle of the panniculus carnosus. Some of the muscles of facial expression in the head are part of the panniculus carnosus.
Neck pain causes can be anything from sleeping in an uncomfortable position to serious neurological concerns. Experts explain causes, diagnosis, and treatments.
Pharyngeal muscles or Branchial muscles are striated muscles of the head and neck. Unlike skeletal muscles that developmentally come from somites, pharyngeal muscles are developmentally formed from the pharyngeal arches. Most of the skeletal musculature supplied by the cranial nerves (special visceral efferent) is pharyngeal.
Further causes of neuromuscular diseases are: Polymyositis. Inflammatory muscle disorders. Polymyalgia rheumatica (or "muscle rheumatism") is an inflammatory condition that mainly occurs in the elderly; it is associated with giant-cell arteritis (It often responds to prednisolone). [18] Polymyositis is an autoimmune condition in which the ...
An increase in neurotransmitters causes spasms to occur in the neck, resulting in spasmodic torticollis. [6] Studies of local field potentials have also shown an increase of 4–10 Hz oscillatory activity in the globus pallidus internus during myoclonic episodes and an increase of 5–7 Hz activity in dystonic muscles when compared to other ...
Those white striations are an indication that the chicken had a muscle disorder called "white striping." It's not harmful for consumption, but it is telling of the conditions the chicken was ...
