A myotome is the group of muscles that a single spinal nerve innervates. [1] Similarly a dermatome is an area of skin that a single nerve innervates with sensory fibers. Myotomes are separated by myosepta (singular: myoseptum). [2] In vertebrate embryonic development, a myotome is the part of a somite that develops into muscle.
When the general visceral sensory fiber is stimulated, the central nervous system does not clearly discern whether the pain is coming from the body wall or from the viscera, so it perceives the pain as coming from somewhere on the body wall, e.g. left arm/hand pain, jaw pain. So the pain is "referred to" the related dermatomes of the same ...
The myotome is that part of a somite that forms the muscles of the animal. [2] Each myotome divides into an epaxial part (epimere), at the back, and a hypaxial part (hypomere) at the front. [2] The myoblasts from the hypaxial division form the muscles of the thoracic and anterior abdominal walls.
The peripheral nervous system (PNS) is divided into the somatic nervous system, the autonomic nervous system, and the enteric nervous system.However, it is the somatic nervous system, responsible for body movement and the reception of external stimuli, which allows one to understand how cutaneous innervation is made possible by the action of specific sensory fibers located on the skin, as well ...
The ankle jerk reflex, also known as the Achilles reflex, occurs when the Achilles tendon is tapped while the foot is dorsiflexed.It is a type of stretch reflex that tests the function of the gastrocnemius muscle and the nerve that supplies it.

The determination of dermomyotome and myotome is regulated by a gene regulatory network that includes a member of the T-box family, tbx6, ripply1, and mesp-ba. [9] Skeletal myogenesis depends on the strict regulation of various gene subsets in order to differentiate the myogenic progenitors into myofibers.
