The proprioceptors
The proprioceptors such as muscle
spindle and golgi tendon organ are sensors located in the limbs. The proprioceptors
give information about muscle length, muscle tension and joint angle which is coordinated
to provide information about the limb’s position in space.

Question :</h2>
Which of the following is not a function of cerebrospinal fluid?
A) acts as a transport medium for waste products
B) provides cushioning for delicate neural tissues
C) provides buoyant support for the brain
D) produces ATP for impulse transmission
E) acts as a transport medium for nutrients
Answer:
D) produces ATP for impulse transmission
Explanation:
CSF doesn't produce ATP for the impulse transmission hence option D is the right option.
Cerebrospinal fluid (CSF) performs following functions :
1) Protects the brain and spinal cord from trauma
2) It supplies nutrients to the nervous tissues
3) It removes the waste products from cerebral metabolism.
Sweat glands is the major function in thermoregulation.
<h2>Density dependent </h2>
Explanation:
Density dependent inhibition is the process exhibited by most normal (anchorage dependent) animal cells in culture that stop dividing once a critical cell density is reached
The critical density is considerably higher for most cells than the density at which a mono-layer is formed
As cells become more numerous, the cell surface proteins of one cell contact the adjoining cells and they signal each other to stop dividing
Normal cells proliferate until they reach finite density but cancer cells are not sensitive to density dependent inhibition
Answer:
Hypothalamic-pituitary-adrenal axis (HPA axis)
Explanation:
- The three-stage process describing the physiological changes that take place in the body when it is under stress is known as general adaptation syndrome (GAS).
- The model describing the three-stage process was given by the scientist Hans Selye.
- According to this model, the responses in the body that occur during stress is regulated by the Hypothalamic-pituitary-adrenal axis (HPA axis) where the brain senses the stress and then the signals travel from the hypothalamus to the pituitary and finally the body releases cortisol from adrenal glands that contributes to the various changes.
