What is the embryonic origin of the diencephalon including thalamus optic chiasma and hypothalamus?
forebrain
Which cells comprise the chain of five cells in the visual pathway beginning with the photoreceptor cell of the retina?
retina-optic nerve-optic chiasma synapse at thalamus-optic radiation-optic cortex
An average of one chiasma during meiosis is equal to how many centiMorgans of genetic distance?
On average, one chiasma is equal to 50 centiMorgans of genetic distance.
Can you see the optic chiasma with an opthalmoscope?
No. The optic chiasm is located at the base of the brain.
What is the midbrain?
The midbrain is the smallest region of the brain that acts as a sort of relay station for auditory and visual information. The midbrain controls many important functions such as the visual and auditory systems as well as eye movement. Portions of the midbrain called the red nucleus and the substantia nigra are involved in the control of body movement. The darkly pigmented substantia nigra contains a large number of dopamine-producing neurons are located. The degeneration of neurons in the substantia nigra is associated with Parkinson's disease.
What is the embryonic origin of the diencephalon including thalamus optic chiasma and hypothalamus?
forebrain
What is the x shaped structure at the bottom of the brain below the hypothalamus and called the 'optic?
chiasma
Which cells comprise the chain of five cells in the visual pathway beginning with the photoreceptor cell of the retina?
retina-optic nerve-optic chiasma synapse at thalamus-optic radiation-optic cortex
What is the site of crossing over between two non-sister chromatids?
Chiasma - The microscopically visible site where crossing over has occurred between chromatids of homologous chromosomes during prophase I of meiosis.
The visual pathway to the occipital lobe of the brain consists most simply of a chain of five neurons beginning with the photoreceptor cell of the retina name them and note their location in the pat?
Retina- optic nerve- optic chiasma- optic tract- synapse in thalamus- optic radiation- optic cortex
What is the definition of chiasm?
Alt. of Chiasma
What is the difference between Chiasma and Chiasmata?
Chiasmata is the plural of chiasma. They both describe the point of crossover between the maternal and paternal chromosomes.
What cant be seen as one looks into the eye with an ophthalmoscope?
Optic Chiasm - a crossing point of the optic nerves.
An average of one chiasma during meiosis is equal to how many centiMorgans of genetic distance?
On average, one chiasma is equal to 50 centiMorgans of genetic distance.
What is the chiasma?
When non-sister chromatids from the homologous chromosome break and rejoin they do so at exactly corresponging sites, so that a cross-shaped structure called chiasma.
What is the crossing of the optic nerves called?
optic chiasma
What is the structure formed by the crossing over of the optic nerves?
Optic Chiasma
