When stimulated by the binding of specific chemicals, the membranes of taste bud receptors and olfactory neurons?

2 answers:

8 0

Taste bud receptors if not stimulated are normally polarized. With the presence of the food, chemicals from the food bind with the cell protein which depolarized the cell membrane receptor. Depolarization will lead into the propagation of electric impulse. This will lead into the creation of sensory impulse. The larger number of the chemicals in the food will lead into a stronger impulse.

The answer is depolarization. Depolarization is the influx of cations, especially sodium ions, from the extracellular fluid into the neuron cell hence generation an electrical impulse along a neuron. The resting potential of neurons is -70mV. When depolarized, the electronegativity in the inside of the neuron cell reduces.

Where do the axons that enter the cortico-spinal tract originate? (The complete answer should include more than one of Brodmann’

torisob [31]

Answer:

From the main motor cortex, Brodmann region 4 premotor areas and the primary somatosensory cortex .

Explanation:

The corticospinal tract originates in many regions of the brain, including

the motor regions,
main somatosensory cortex
pre-motor regions

The corticospinal tract allows for voluntary control of motor functions.

30% of the neurons in the corticospinal regions are found in the primary motor cortex. 40% are split up in several regions; the parietal lobe, somatosensory cortex and the cingulate gyrus.

The axon is a tube enclosed in and insulated by the myelin sheath. It serves as a link to impulses for certain neurons that often comprise axon hillocks that are junctions between the axon and the cell body.
