Spinal Cord Vascular Diseases
|
D020758 |
[Pathological processes involving any of the BLOOD VESSELS feeding the SPINAL CORD, such as the anterior and paired posterior spinal arteries or their many branches. Disease processes may include ATHEROSCLEROSIS; EMBOLISM; and ARTERIOVENOUS MALFORMATIONS leading to ISCHEMIA or HEMORRHAGE into the spinal cord (hematomyelia).

Spinal Cord Ventral Horn
|
D066151 |
[One of three central columns of the spinal cord. It is composed of GRAY MATTER spinal laminae VIII and IX.

|
Spinal Curvatures
|
D013121 |
[Deformities of the SPINE characterized by abnormal bending or flexure in the vertebral column. They may be bending forward (KYPHOSIS), backward (LORDOSIS), or sideway (SCOLIOSIS).

[Diseases involving the SPINE.

Spinal Dysraphism
|
D016135 |
[Congenital defects of closure of one or more vertebral arches, which may be associated with malformations of the spinal cord, nerve roots, congenital fibrous bands, lipomas, and congenital cysts. These malformations range from mild (e.g., SPINA BIFIDA OCCULTA) to severe, including rachischisis where there is complete failure of neural tube and spinal cord fusion, resulting in exposure of the spinal cord at the surface. Spinal dysraphism includes all forms of spina bifida. The open form is called SPINA BIFIDA CYSTICA and the closed form is SPINA BIFIDA OCCULTA. (From Joynt, Clinical Neurology, 1992, Ch55, p34)

Spinal Fractures
|
D016103 |
[Broken bones in the vertebral column.

|
Spinal Fusion
|
D013123 |
[Operative immobilization or ankylosis of two or more vertebrae by fusion of the vertebral bodies with a short bone graft or often with diskectomy or laminectomy. (From Blauvelt & Nelson, A Manual of Orthopaedic Terminology, 5th ed, p236; Dorland, 28th ed)

D013124 |
[Injuries involving the vertebral column.

Spinal Muscular Atrophies of Childhood
|
D014897 |
[A group of recessive inherited diseases that feature progressive muscular atrophy and hypotonia. They are classified as type I (Werdnig-Hoffman disease), type II (intermediate form), and type III (Kugelberg-Welander disease). Type I is fatal in infancy, type II has a late infantile onset and is associated with survival into the second or third decade. Type III has its onset in childhood, and is slowly progressive. (J Med Genet 1996 Apr:33(4):281-3)

Spinal Neoplasms
|
D013125 |
[New abnormal growth of tissue in the SPINE.
] |
|
Spinal Nerve Roots
|
D013126 |
[Paired bundles of NERVE FIBERS entering and leaving the SPINAL CORD at each segment. The dorsal and ventral nerve roots join to form the mixed segmental spinal nerves. The dorsal roots are generally afferent, formed by the central projections of the spinal (dorsal root) ganglia sensory cells, and the ventral roots are efferent, comprising the axons of spinal motor and PREGANGLIONIC AUTONOMIC FIBERS.

|
Spinal Nerves
|
D013127 |
[The 31 paired peripheral nerves formed by the union of the dorsal and ventral spinal roots from each spinal cord segment. The spinal nerve plexuses and the spinal roots are also included.

|
Spinal Osteochondrosis
|
D055035 |
[A bone disorder involving ossification centers (EPIPHYSES) of the VERTEBRAL COLUMN.
] |
|
Spinal Osteophytosis
|
D013128 |
[Outgrowth of immature bony processes or bone spurs (OSTEOPHYTE) from the VERTEBRAE, reflecting the presence of degenerative disease and calcification. It commonly occurs in cervical and lumbar SPONDYLOSIS.
] |
|
Spinal Puncture
|
D013129 |
[Tapping fluid from the subarachnoid space in the lumbar region, usually between the third and fourth lumbar vertebrae.
] |
|
Spinal Stenosis
|
D013130 |
[Narrowing of the spinal canal.
] |
|
Spindle Apparatus
|
D008941 |
[A microtubule structure that forms during CELL DIVISION. It consists of two SPINDLE POLES, and sets of MICROTUBULES that may include the astral microtubules, the polar microtubules, and the kinetochore microtubules.
, Microtubular array that forms at the start of MEIOSIS and acts to separate sister CHROMATIDS during meiotic division. It is similar in structure and function to the MITOTIC SPINDLE APPARATUS that forms during MITOSIS.

|
Spindle Pole Bodies
|
D064048 |
[Microtubule organizing centers of FUNGI and DIATOMS. They are embedded in the NUCLEAR ENVELOPE and evolve into the spindle apparatus during CELL DIVISION.
] |
|
Spindle Poles
|
D064047 |
[The sites in a dividing cell where the minus ends of the spindle MICROTUBULES assemble and where the separated sister CHROMATIDS converge.

|
Spine
|
D013131 |
[The spinal or vertebral column.
