What is the major relay station for sensory information ascending to primary sensory areas of the cerebral cortex?

The thalamus encloses the shallow third ventricle of the brain, and is the relay station for sensory impulses passing upwards to the sensory cortex.

Do Second-order neurons of ascending sensory pathways always decussate.?
No! Only neurons of the specific (lemniscal) & non-specific (anterolateral) pathways decussate and sensation is therfore interpreted in the opposite cerebral hemisphere.Spinocerebellar ascending pathways transmit proprioceptive sensory stimuli to the same side of the cerebellum.
What carries sensory information to the spinal cord?
The major descending motor tract FROM the cerebrum is the corticospinal tract. The major ascending sensory tracts TO the cerebrum are the sensorimotor tract and the dorsal column lemniscal system.
Is it true that information flows from the sensory receptors to the appropriate primary sensory cortex?
Yes
Where does the neurons in the primary sensory cortex receive somatic information from?
Most of the sensory information first goes through the thalamus. touch, pressure, pain, taste, and temperature receptors.
The primary somatosensory area of the cerebral hemisphere is found in the precentral gyrus. true or false?
no the precentral gyrus is the primarymotor area and postcentral gyrus is the sensory area
Ascending pathways in the spinal cord convey what?
Sensory information
Do descending fiber tracts of the spinal cord carry sensory or motor information?
The ascending tracts carry information to the brain.
What is part of the lobe responsible for the integration of sensory-motor information?
Cerebral
What does not use a nonspecific ascending pathway to transmit sensory information to the brain?
Arousal.
Do Second-order neurons of ascending sensory pathways always decussate.?
No! Only neurons of the specific (lemniscal) & non-specific (anterolateral) pathways decussate and sensation is therfore interpreted in the opposite cerebral hemisphere.Spinocerebellar ascending pathways transmit proprioceptive sensory stimuli to the same side of the cerebellum.
Which of the areas of the cerebral cortex receives sensation?
The primary sensory area which is located on the postcentral gyrus of the parietal lobe.
What separates the sensory strip from the motor strip?
The primary somatosensory cortex, or sensory strip, is responsible for processing sensory information from the body. In contrast, the primary motor cortex, or motor strip, is involved in planning and executing voluntary movements. These areas are adjacent to each other in the brain's cerebral cortex, but each has distinct functions related to sensation and movement.
What carries sensory information to the spinal cord?
The major descending motor tract FROM the cerebrum is the corticospinal tract. The major ascending sensory tracts TO the cerebrum are the sensorimotor tract and the dorsal column lemniscal system.
Is it true that information flows from the sensory receptors to the appropriate primary sensory cortex?
Yes
The parietal lobe processes sensory informstion from the?
The parietal lobe of the cerebral cortex processes sensory information from various parts of the body including the skin.
What is the difference between ascending tracts and descending tracts of the spinal cord?
ascending carry sensory information toward the brain.descending convey motor command to the spinal cord.
What are the ascending fibres of projection fibres?
They are fibres which radiate from thalamus and metathalamus to the cerebral cortex. They include:Anterior thalamic radiationsuperior thalamic (sensory) radiationposterior thalamic radiation, which consists of = optic + auditory radiations
