The central nervous system (CNS) consists of the brain, brainstem, cerebellum, and spinal cord ( Fig. 3-1 ). (mhmedical.com)
Before devoting the rest of this chapter to the internal and external structures of the brain, a brief orientation to the brainstem, spinal cord, and cerebellum is provided here. (mhmedical.com)
The cerebellum lies posterior to the brainstem and inferior to the posterior aspect of the cerebral hemispheres, and is connected to the brainstem by way of the three cerebellar peduncles (see Ch. 8 ). (mhmedical.com)
The brainstem and the cerebellum constitute the structures of the posterior fossa. (pediagenosis.com)
The cerebellum is connected to the brainstem via three pairs of cerebellar peduncles, and is involved in the coordination of move- ment (see Chapter 40). (pediagenosis.com)

The stimulation sites typically used for clinical diagnostic SEP studies are the median nerve at the wrist, the common peroneal nerve at the knee, and the posterior tibial nerve at the ankle. (medscape.com)

Recordings of SEPs to stimulation of the ulnar nerves at the wrists are useful for intraoperative monitoring when the mid-cervical spinal cord or parts of the brachial plexus are at risk. (medscape.com)
Ulnar nerve SEPs are preferred to median nerve SEPs for assessing the lower cervical spinal cord, especially during intraoperative monitoring when this part of the spinal cord is at risk, because the ulnar nerve originates from spinal roots C8-T1, whereas the median nerve originates from C6-T1.

Clinicians should report to their local and state health departments patients aged ≤21 years with 1) acute onset of focal limb weakness occurring on or after August 1, 2014, and 2) magnetic resonance imaging showing a spinal cord lesion largely restricted to gray matter. (cdc.gov)
Mimics of GBS and MFS can broadly be divided into those presenting with symmetrical limb weakness and those presenting with brainstem signs. (bmj.com)
So many English words come from the Latin root ponere (pon- or pos-) For example: The opposing team imposed their will until they exposed their weakness. (masterhitech.ru)

Nerve fiber degeneration and/or glial reactions may be seen in nerves, dorsal spinal nerve roots, spinal cord, and occasionally brainstem. (bvsalud.org)
3,4) In previous reports of experimental Talfan disease, axonal degeneration was seen in the ventral root and sciatic nerves. (askjpc.org)
1) In contrast, demyelination and axonal degeneration in the present cases, which resulted from a natural outbreak in Japan, appeared in the whole white matter, and in either the ventral or dorsal root. (askjpc.org)
In the late 1960s, neurophysiologic testing allowed the classification of CMT into 2 groups, one with slow nerve conduction velocities and histologic features of a hypertrophic demyelinating neuropathy (hereditary motor and sensory neuropathy type 1 or CMT1) and another with relatively normal velocities and axonal and neuronal degeneration (hereditary motor and sensory neuropathy type 2 or CMT2).

Cranial nerves are the 12 nerves of the peripheral nervous system that emerge from the foramina and fissures of the cranium.Their numerical order (1-12) is determined by their skull exit location (rostral to caudal). (spagades.com)
They pass through skull foramina, fissures, or canals to exit 5th Cranial nerve. (spagades.com)

The first two actually emerge from the telencephalon and diencephalon , but the rest of the nerves, nerves 3 to 12, emerge from the brainstem . (anatomyzone.com)

Examination of the cranial nerves allows one to "view" the brainstem all the way from its rostral to caudal extent. (spagades.com)
On completion of this module you will be able to perform spinal, epidural and caudal anaesthesia safely. (developinganaesthesia.com)
Neuraxial anaesthesia or central neural blockade encompasses spinal, epidural and caudal administration of local anaesthetic and opioid medications. (developinganaesthesia.com)
