Temporal hemiretina
|
|
Temporal hemiretina That portion of the retina that lies lateral to the fovea.
RELATED TERMS--------------------------------------
Retina
A membrane lining the inside of the back of the eye that contains light-sensitive nerve cells that convert focused light into nerve impulses, making vision possible.
Lateral
Toward the side, sideways.
Fovea
A central portion of the retina and macula that contains only cones. The fovea is the only part of the eye that is capable of 20/20 or better vision.
SIMILAR TERMS--------------------------------------
Temperament
Constitutional predisposition to react in a particular way to stimuli.
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.
Temple University Health Center
The Temple University Health Center is a hospital in Philadelphia, Pennsylvania, United States.
Temporal
Having to do with the side of the head.
Temporal arteries
Vessels located over the temples on each side of the head, that supply blood to part of the head.
Temporal arteritis
A vasculitic disorder which presents with head pain and scalp tenderness and a high ESR. Sudden loss of vision may occur due to retinal artery occlusion. Part of the polymyalgia rheumatica disease spectrum. Also known as cranial or giant cell arteritis.
Temporal lobe
In the brain, the part of each cerebral hemisphere that is named for its location internal to the temple.
Temporal lobe trauma
Injury to the temporal lobe of the brain, of either external or internal origin, with which there is associated an increased risk of temporal lobe epileptic seizures (psychomotor epilepsy, complex partial seizure) and, rarely, associated paraphilic attacks.
TEMPOROMANDIBULAR DISORDER / TM
Sometimes called "TMJ disease" or TM dysfunction, this is a painful condition of the jaw joint which can cause a variety of symptoms such as headaches, facial pain, tenderness or ringing in the ears, clicking or popping of the jaw, or pain when opening and closing the mouth. These problems are referred to as TM disorders. The causes of TM are not well understood and there are varying opinions on how to most effectively diagnose and treat these conditions. The causes of TM disorder may include trauma, arthritis and stress, or a combination thereof. Oral habits such as clenching or bruxing the teeth especially at night when a patient is asleep can slowly cause the muscles to fatigue and spasm without the awareness of the patient. Treatment is usually done in a step-by-step plan, as only minor corrective treatment may be necessary. If pain persists some patients may need more advanced treatment such as medication, psychological intervention, physical therapy or splint therapy. In some severe cases surgery may be needed to correct the joint.
Temporomandibular joint
TMJ. The joint between the lower jaw and the side of the head, located just in front of the ear.
PREVIOUS AND NEXT TERMS--------------------------------------
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
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.
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
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.
Thoracentesis
Puncture of the pleural cavity.
Thrombocytopenia
Decrease in blood platelets.
