Pani-rosa [81]

After the cerebellum receives proprioceptive information from muscles carrying out a voluntary movement, where does it send corrective feedback to primary motor cortex and cerebral nuclei.

The cerebellum, also known as the corticocerebellum, has a close connection to the regulation of movement timing, rate, range, length, direction, and strength. The cerebellum receives information from the command neurons and also obtains feedback (afferent) from the proprioceptive terminals of the muscles, tendons and joints regarding what the actual movements produce .

All these information are combined and the correction signals are given to the motor cortex. The motor nuclei of the cranial nerves and spinal cord exert the lowest level of motor control. Through the closed feedback loop, this occurs.

How does cell transport like diffusion impact homeostasis
Reil [10]

Answer:

homeostasis is the state of steady internal physical and chemical conditions maintained by living system.

Diffusion is an important process for living things; it is how substances move in and out of cells.

Diffusion helps maintain homeostasis by creating specific concentrations of molecules inside the body compared to outside and Cells in homeostasis are successfully maintaining the internal conditions necessary for basic functioning

The cell needs to export waste and other molecules, and import fuels and fluids. Plasma membranes allow water, oxygen and carbon dioxide to pass through by osmosis, or passive diffusion.
