What genes are responsible for neuronal migration disorders?
The most well characterized genes include DCX on the X chromosome, responsible for double cortex syndrome, and LIS1 on chromosome 17, the first gene identified for lissencephaly.
Do the spinal funiculi contain fiber tracts or neuronal cell bodies?
"The three funiculi contain many fiber tracts. Each fiber tract is composed of axons that have all similar destinations and functions."Citation:Marieb, Elaine N., Patricia Brady Wilhelm, and Jon Mallatt. Human Anatomy. Sixth Edition Media Update. San Francisco: Pearson Education Inc. , 2010. pg. 376.
Are extrapyramidial tracts nerve tracts that the corticospinal tracts that transmit impulses into the spinal cord?
yes it is
What is the difference between pyramidal and extrapyramidal system?
The Similarity: Pyramidal and extra-pyramidal system are the descending tracts (motor tracts) of spinal cord.The Difference:1) Their tracts -Pyramidal system = lateral and anterior corticospinal tracts + corticobulbar tractExtra-pyramidal system = rubrospinal + olivospinal + lateral and medial reticulospinal + tectospinal + vestibulospinal tracts2) "Extrapyramidal tracts" don't reach their targets by traveling through the "pyramids of medulla". Pyramidal tracts go through the pyramids of medulla.3) Pyramidal tracts may directly innervate motor neurons of spinal cord or brainstem (anterior horn cells or certain cranial nerve nuclei). But, extrapyramidal tractsindirectly control the anterior horn cells (for modulation and regulation)4) Pyramidal system is responsible for fine, isolated, precise and specific movements. Extrapyramidal system is responsible for gross, syngergic movements which require the activity of large groups of muscles
Site of the nucleus and most important metabolic area?
Neuronal cell body
What is a Neuronal cell body?
The soma
What are neuronal varicosities?
vb cvbcbcxn
What is the main role of Gamma Amino-Butyric Acid?
The main role of Gamma Amino-Butyric Acid is to regulate the neuronal excitability in the nervous system. It is also responsible for regulating muscle tone.
What is the importance in a reverberation neuronal pool?
there is no importance
What transmits impulses of crude touch pain and temperature cuneatus?
The Cuneate Fasciculus Spinal Tracts are responsible for transmiting crude touch pain and temperature. The cuneate fasciculus is responsible for relaying sensory signals from the thoracic and cervical areas of the body to the brain.
What is the prognosis for patients with neuronal migration disorder?
Due to the congenital nature of neuronal migration disorders, most patients do not recover from their symptoms. The course of disease tends to be static.
When was Deep Tracts of Hell created?
Deep Tracts of Hell was created in 1998-07.
