Tectospinal tract
|
|
Tectospinal tract Axons from the colliculus to the upper spinal cord where the neck motor neurons are located. Involved in reflex control of head and neck movements.
RELATED TERMS--------------------------------------
Cord
1. In anatomy, a long ropelike structure. 2. Short for the spinal cord or the umbilical cord.
Reflex
An automatic, involuntary movement.
SIMILAR TERMS--------------------------------------
Tectopontine tract
Relays information from the colliculus to the cerebellum for further coordination of eye and head movement.
PREVIOUS AND NEXT TERMS--------------------------------------
Trisomy 18
A severe birth defect caused by a chromosomal abnormality. Children with the disorder have small eyes,abnormally formed ears, and heart problems, are severely mentally retarded, and rarely live past one year.
Tuboplasty
A surgical procedure to unblock Fallopian tubes. Can also be used to reverse a tubal ligation.
Tympanostomy
Tiny drainage tubes surgically inserted in the middle ear to relieve chronic ear infections.
Tapetum
Silvery lining behind the retina in some animals active in dim light. Reflects light back through the eye and allows the photoreceptors a second chance to absorb photons.
Tectopontine tract
Relays information from the colliculus to the cerebellum for further coordination of eye and head movement.
Tectospinal tract
Template matching
An object recognition method. Incoming patterns are matched against a set of templates. If there is sufficient overlap between object and template, a match is signaled. Of limited use, primarily in alphanumeric character recognition.
Temporal hemiretina
That portion of the retina that lies lateral to the fovea.
Tetrachromatic color vision
Color vision based on four cone photoreceptor pigments in the retina. The fourth cone type is sensitive to U.V. light and seen in goldfish.
Texton
The basic textural elements of pre-attentive vision such as elongated blobs or line segments and their terminators which are important for segregation of textures.
Transducin
A regulatory g-protein in photoreceptors which stimulates phosphodiesterase molecules and acts as an amplifier of the incoming light signal.
