Is corticospinal tract an indirect descending tract?
no
What is the order of the neural pathway?
retina optic nerve optic chiasma optic tract lateral geniculate nucleus optic radiations primary visual cortex
What connects the dentate nucleus to the thalamus?
The pathway that connects the dentate nuclei to the ventro-lateral thalamus is called the dentatothalamic tract. This is contained within the superior cerebellar peduncles.
What is descending tract and one ascending tract in upper motor neuron and lower motor neuron?
central nervous system (CNS) is the descending tract and one ascending tract in upper motor neuron and lower motor neuron.
What is the anterior visual pathway?
The anterior visual pathway refers to the pathway that visual information takes from the eyes to the visual cortex in the brain. It includes the optic nerves, optic chiasm, optic tracts, and lateral geniculate nucleus. This pathway is responsible for transmitting visual signals from the retina to the brain for processing and interpretation.
what is the difference between ascending and descending tract?
An ascending tract goes upward. The descending tract goes downward.
Is corticospinal tract an indirect descending tract?
no
What track is the major descending voluntary motor tract?
The corticospinal tract
What is the order of the neural pathway?
retina optic nerve optic chiasma optic tract lateral geniculate nucleus optic radiations primary visual cortex
What connects the dentate nucleus to the thalamus?
The pathway that connects the dentate nuclei to the ventro-lateral thalamus is called the dentatothalamic tract. This is contained within the superior cerebellar peduncles.
What is descending tract and one ascending tract in upper motor neuron and lower motor neuron?
central nervous system (CNS) is the descending tract and one ascending tract in upper motor neuron and lower motor neuron.
What is optic tract?
An Optic Tract is the pathway between the optic chiasma and the brain.
Pain pathway generation and processing of fast pain impulse?
there are pain receptors in the skin, when we get any pain stimulus it pass through this receptors and goes to the CNS. the stimulus pass through the dorsal nerve root to the marginal nucleus and substenti gelatinosa of Rolando which are the nucleus of the spinal cord. from there the pain changes its side and goes to the other side and travel through the lateral spinothalamic tract(paleospinothalamic tract and neospinothalamic tract) by this pathway it reaches to the higher centers of brain like limbic system, thalamus and to the paraqidactal gray matter. from these nucleus it radiates to the sensory cortex, this is how we feel the pain.
What is the difference between corticobulbar tract and cortico spinal tract?
corticospinal tracts are the tracts of the upper motor neurons which originate in the cortex,(precentral gyrus). They terminate in the spinal cord by synapsing with the lower motor neurons either directly or through an interneuron. lesion to the corticospinal tract results in Spastic paralysis on the opp side if the lesion is above pyramidal decussation or before crossing over. Positive Babinski's sign loss of fine coordination in the distal limbs such as piano playing or typing

A group of neurons with shared functions in the CNS is called a?
nerve tract
Part of the food tube where the GI tract and the respiratory tract cross each other?
The pharynx is common to both the respiratory pathway ( pharynx -> larnyx -> trachea -> pulmonary bronchi ) and the digestive pathway ( pharynx -> esophogus->stomach).
