  2. Dorsal root of spinal nerve - Wikipedia

    en.wikipedia.org/wiki/Dorsal_root_of_spinal_nerve

    The dorsal root of spinal nerve (or posterior root of spinal nerve or sensory root) [1] is one of two "roots" which emerge from the spinal cord. It emerges directly from the spinal cord, and travels to the dorsal root ganglion. Nerve fibres with the ventral root then combine to form a spinal nerve.

  3. Dorsal ramus of spinal nerve - Wikipedia

    en.wikipedia.org/wiki/Dorsal_ramus_of_spinal_nerve

    A spinal nerve splits within the intervertebral foramen to form a dorsal ramus and a ventral ramus. The dorsal ramus then turns to course posterior-ward before splitting into a medial branch and a lateral branch. Both these branches provide motor innervation to deep back muscles. In the neck and upper back, the medial branch is also responsible ...

  4. Dorsal nerve of the penis - Wikipedia

    en.wikipedia.org/wiki/Dorsal_nerve_of_the_penis

    The dorsal nerve of the penis is the deepest of three divisions of the pudendal nerve; it accompanies the internal pudendal artery along the ramus of the ischium; it then runs forward along the margin of the inferior ramus of the pubis, between the superior and inferior layers of the fascia of the urogenital diaphragm.

  5. Dorsal column–medial lemniscus pathway - Wikipedia

    en.wikipedia.org/wiki/Dorsal_column–medial...

    At the medial lemniscus, axons from the leg are more ventral, and axons from the arm are more dorsal. Fibres from the trigeminal nerve (supplying the head) come in dorsal to the arm fibres, and travel up the lemniscus too. The medial lemniscus rotates 90 degrees at the pons. The secondary axons from neurons giving sensation to the head, stay at ...

  6. Spinal nerve - Wikipedia

    en.wikipedia.org/wiki/Spinal_nerve

    Spinal nerve Typical spinal nerve location Each spinal nerve is a mixed nerve , formed from the combination of nerve root fibers from its dorsal and ventral roots . The dorsal root is the afferent sensory root and carries sensory information to the brain.

  7. Dorsal scapular nerve - Wikipedia

    en.wikipedia.org/wiki/Dorsal_scapular_nerve

    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, with pain and limited motion.

  8. Dorsal nerve cord - Wikipedia

    en.wikipedia.org/wiki/Dorsal_nerve_cord

    The dorsal nerve cord is located dorsal to the notochord and thus also to the gut tube (hence the name). It is formed from clustered neuronal differentiation at the axial region of the ectoderm, known as the neural plate.

  9. Spinocerebellar tracts - Wikipedia

    en.wikipedia.org/wiki/Spinocerebellar_tracts

    The spinocerebellar tracts are nerve tracts originating in the spinal cord and terminating in the same side (ipsilateral) of the cerebellum. The two main tracts are the dorsal spinocerebellar tract, and the ventral spinocerebellar tract. Both of these tracts are located in the peripheral region of the lateral funiculi (white matter columns). [1]
