Where do the axons that enter the cortico-spinal tract originate? (The complete answer should include more than one of Brodmann’
torisob [31]

Answer:

<u>From the main motor cortex, Brodmann region 4 premotor areas and the primary somatosensory cortex .</u>

<u />

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.

Describe how alveoli are adapted for gas exchange( 4 marks)​
SashulF [63]

Answer:

they give the lungs a really big surface area. they have moist, thin walls (just one cell thick) they have a lot of tiny blood vessels called capillaries.

The walls of the alveoli are only one cell thick. This makes the exchange surface very thin - shortening the diffusion distance across which gases have to move. Each alveolus is surrounded by blood capillaries which ensure a good blood supply.Adaptations of the alveoli:

Thin walls - alveolar walls are one cell thick providing gases with a short diffusion distance. Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls - allow gases to pass through.
