A myotome (greek: myo=muscle, tome = a section, volume) is defined as a group of muscles which is innervated by single spinal nerve root. Myotome testing is an essential part of neurological examination when suspecting radiculopathy.

2023年7月20日 · A myotome is a group of muscles innervated by the ventral root a single spinal nerve. This term is based on the combination of two Ancient Greek roots; “myo-” meaning “muscle”, and “tome”, a “cutting” or “thin segment”. Like spinal nerves, myotomes are organised into segments because they share a common origin.

2018年5月14日 · Myotomes. A myotome is a group of muscles innervated by a single spinal nerve. This list details some important myotome nerve roots and the actions that their associated muscles produce: C4: shoulder shrugs; C5: shoulder abduction and external rotation; elbow flexion; C6: wrist extension; C7: elbow extension and wrist flexion

2018年10月1日 · In simple words myotome is defined as a group of muscles which is innervated by single spinal nerve root. Myotome is a part of somatic nervous system and the somatic nervous system is a part of peripheral nervous system.

In anatomy the myotome is the motor equivalent of a dermatome. Each muscle in the body is supplied by one or more levels or segments of the spinal cord and by their corresponding spinal nerves. A group of muscles innervated by the motor fibres of a …

2024年7月28日 · Myotomes are groups of muscles that receive signals from a single spinal nerve root. These muscle groups work together to perform a specific motor function. If you have signs of nerve damage, your healthcare provider or physical therapist may do myotome testing.

2022年12月15日 · In this article we shall look at the embryonic origins of myotomes, their distribution in the adult and their clinical uses. Explore, cut, dissect, annotate and manipulate our 3D models to visualise anatomy in a dynamic, interactive way. Skeletal muscle development can be traced to the appearance of somites.

Cells along the craniomedial edge of the dermomyotome elongate in a cranial to caudal direction and are collectively called the myotome. These cells will form the epaxial muscles, which are dorsolateral to the vertebrae. The myotome of one somite soon encounters the myotomes cephalic and caudal to it.

Myotomes, dermatomes, and sclerotomes are three distinct divisions of the myotome system. Myotomes are a group of skeletal muscle cells that control the movement of myofascial (muscle) tissue. Dermatomes are a type of myotome that provides sensation in the skin.
