posterior horn

pos·te·ri·or horn

1. the occipital or posterior division of the lateral ventricle of the brain, extending backward into the occipital lobe;
See also: posterior column. 2. the posterior horn or gray column of the spinal cord as appearing in cross section. The posterior horn [TA] or dorsal horn [TAalt] contains spinal laminae I-VI [TA] of Rexed. The nuclei of the posterior horn are the marginal nucleus [TA] (nucleus marginalis [TA]), gelatinous substance [TA] (substantia gelatinosa [TA]), nucleus proprius [TA], secondary visceral grey substance [TA] (substantia visceralis secundaria [TA]), internal basilar nucleus [TA] (nucleus basilar internus [TA]), medial cervical nucleus [TA] (nucleus cervicalis medialis [TA]), posterior nucleus of lateral funiculus [TA] (nucleus posterior funiculi lateralis [TA]), and the lateral cervical nucleus. Synonym(s): cornu posterius ventriculi lateralis [TA], cornu posterius [TA], occipital horn [TA], cornu of spinal cord

pos·te·ri·or horn

(pos-tēr'ē-ŏr hōrn) The posterior or occipital division of the lateral ventricle of the brain, extending backward into the occipital lobe; the posterior gray column of the spinal cord as it appears in cross section.
Synonym(s): cornu posterius.

horn

(horn) A cutaneous outgrowth composed chiefly of keratin; a hornlike projection. Synonym: cornu

horn of Ammon

Hippocampus.

anterior horn

The main column of neuron cell bodies and unmyelinated cell processes ( gray matter) running through the ventral quadrant of each half of the spinal cord. In stained cross-sections of spinal cord, the gray matter forms the rough shape of a butterfly; the anterior horns are the lower wings. Synonym: ventral horn See: spinal cord

cicatricial horn

A cutaneous horn originating in scar tissue.

cutaneous horn

A hard, horny outgrowth from the skin. It is slow-growing, benign, and may be small or large, 10 to 12 cm, in diameter.

dorsal horn

The main column of neuron cell bodies and unmyelinated cell processes (ie, gray matter) running through the dorsal quadrant of each half of the spinal cord. In stained cross-sections of spinal cord, the gray matter forms the rough shape of a butterfly; the dorsal horns are the upper wings. Synonym: posterior horn See: spinal cord

intermediolateral horn

Lateral horn.

lateral horn

A column of neuron cell bodies and unmyelinated cell processes (ie, gray matter) running through the lateral quadrant of spinal cord segments C8–L2 In stained cross-sections of spinal cord, the lateral horns form a small bulge of gray matter between the dorsal and ventral horns. The lateral horns contain the preganglionic cell bodies of the sympathetic nervous system. Synonym: intermediolateral horn; intermediolateral cell column; zona intermedia See: spinal cord

posterior horn

Dorsal horn.

sebaceous horn

A hard protrusion from a sebaceous gland.

uterine horn

Either of the two upper corners of the uterus into which the uterine tubes enter.

ventral horn

Anterior horn.

warty horn

A hard outgrowth from a wart.
