The second law of thermodynamics states that not all of the energy is used because some of the energy is lost in the form of heat. The lost heat energy is an unusable form of energy, and it causes an increase in the entropy of the universe. Thus, no energy transfer process is efficient due to the loss of energy.

Sensing the position and movement of individual body parts is an example of which sense?

serg [7]

Answer:

The Vestibular sense is responsible for our sense of spatial orientation or balance.
The Auditory sense is responsible for the perception of sounds.
The Umami Olfactory sense is responsible for our sense of smell and taste.

So the answer is (a), kinesthesic. It is thanks to the kinesthetic sense that we can go up stairs easily without stopping to see and carefully control the movement of each of our legs.

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.
