Anatomical terms of neuroanatomy. [edit on Wikidata] The dorsal scapular nerve is a branch of the brachial plexus, usually derived from the ventral ramus of cervical nerve C5. It provides motor innervation to the rhomboid major muscle, rhomboid minor muscle, and levator scapulae muscle. Dorsal scapular nerve syndrome can cause a winged scapula ...
The thoracodorsal nerve arises from the posterior cord of the brachial plexus. It is derived from their ventral rami (in spite of the fact that the latissimus dorsi is found in the back) of cervical nerves C6-C8. [1][3] It is derived from fibres of the posterior divisions of all three trunks of the brachial plexus. [4]
The hypaxial muscles are located on the ventral side of the body, often below the horizontal septum in many species (primarily fish and amphibians). In all species, the hypaxial muscles are innervated by the ventral ramus (branch) of the spinal nerves, while the epaxial muscles are innervated by the dorsal ramus. [citation needed]
The ventral ramus (pl.: rami) (Latin for 'branch') is the anterior division of a spinal nerve. The ventral rami supply the antero-lateral parts of the trunk and the limbs. They are mainly larger than the dorsal rami. Shortly after a spinal nerve exits the intervertebral foramen, it branches into the dorsal ramus, the ventral ramus, and the ...
The suboccipital triangleis a region of the neckbounded by the following three muscles of the suboccipital group of muscles: Rectus capitis posterior major- above and medially. Obliquus capitis superior- above and laterally. Obliquus capitis inferior- below and laterally. (Rectus capitis posterior minor is also in this region but does not form ...
A selective dorsal rhizotomy (SDR), also known as a rhizotomy, dorsal rhizotomy, or a selective posterior rhizotomy, is a neurosurgical procedure that selectively cuts problematic nerve roots in the spinal cord. [3][note 1] This procedure has been well-established in the literature as a surgical intervention and is used to relieve negative ...
It is a remnant of part of biceps femoris muscle. The sacrotuberous ligament is attached by its broad base to the posterior superior iliac spine, the posterior sacroiliac ligaments (with which it is partly blended), to the lower transverse sacral tubercles and the lateral margins of the lower sacrum and upper coccyx.
Spinal nerve. A spinal nerve is a mixed nerve, which carries motor, sensory, and autonomic signals between the spinal cord and the body. In the human body there are 31 pairs of spinal nerves, one on each side of the vertebral column. [1][2] These are grouped into the corresponding cervical, thoracic, lumbar, sacral and coccygeal regions of the ...
