(gcide) | Spinal \Spi"nal\, a. [L. spinalis, fr. spina the spine: cf. F.
spinal. See Spine.]
1. (Anat.) Of, pertaining to, or in the region of, the
backbone, or vertebral column; rachidian; vertebral.
[1913 Webster]
2. Of or pertaining to a spine or spines.
[1913 Webster]
Spinal accessory nerves, the eleventh pair of cranial
nerves in the higher vertebrates. They originate from the
spinal cord and pass forward into the skull, from which
they emerge in company with the pneumogastrics.
Spinal column, the backbone, or connected series or
vertebrae which forms the axis of the vertebrate skeleton;
the spine; rachis; vertebral column.
Spinal cord, the great nervous cord extending backward from
the brain along the dorsal side of the spinal column of a
vertebrate animal, and usually terminating in a threadlike
appendage called the filum terminale; the spinal, or
vertebral, marrow; the myelon. The nervous tissue consists
of nerve fibers and nerve cells, the latter being confined
to the so-called gray matter of the central portions of
the cord, while the peripheral white matter is composed of
nerve fibers only. The center of the cord is traversed by
a slender canal connecting with the ventricles of the
brain.

n 1: a major part of the central nervous system which conducts
sensory and motor nerve impulses to and from the brain; a
long tubelike structure extending from the base of the
brain through the vertebral canal to the upper lumbar
region [syn: spinal cord, medulla spinalis] |

bulb of the spinal cord
(gcide) | Medulla \Me*dul"la\, n. [L.]
1. Marrow; pith; hence, essence. [Obs.] --Milton.
[1913 Webster]
2. (Anat.) The marrow of bones; the deep or inner portion of
an organ or part; as, the medulla, or medullary substance,
of the kidney; specifically, the medula oblongata.
[1913 Webster]
3. (Bot.) A soft tissue, occupying the center of the stem or
branch of a plant; pith.
[1913 Webster]
4. See medulla oblongata.
[PJC]
Medulla oblongata. [L., oblong medulla] (Anat.), the
posterior part of the brain connected with the spinal
cord. It includes all the hindbrain except the cerebellum
and pons, and from it a large part of the cranial nerves
arise. It controls very largely respiration, circulation,
swallowing, and other functions, and is the most vital
part of the brain; -- called also {bulb of the spinal
cord}. See Brain.
[1913 Webster]Bulb \Bulb\ (b[u^]lb), n. [L. bulbus, Gr. bolbo`s: cf. F.
bulbe.]
1. (Bot.) A spheroidal body growing from a plant either above
or below the ground (usually below), which is strictly a
bud, consisting of a cluster of partially developed
leaves, and producing, as it grows, a stem above, and
roots below, as in the onion, tulip, etc. It differs from
a corm in not being solid.
[1913 Webster]
2. (Anat.) A name given to some parts that resemble in shape
certain bulbous roots; as, the bulb of the aorta.
[1913 Webster]
Bulb of the eye, the eyeball.
Bulb of a hair, the "root," or part whence the hair
originates.
Bulb of the spinal cord, the medulla oblongata, often
called simply bulb.
Bulb of a tooth, the vascular and nervous papilla contained
in the cavity of the tooth.
[1913 Webster]
3. An expansion or protuberance on a stem or tube, as the
bulb of a thermometer, which may be of any form, as
spherical, cylindrical, curved, etc. --Tomlinson.
[1913 Webster]
3. a light bulb.
