Question

Identify the parts of brain concerned with
Control pupil size
Muscular coordination

Answer 1

Answer:

Explanation:

Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.

Cerebellum: is located under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance.

Brainstem: acts as a relay center connecting the cerebrum and cerebellum to the spinal cord. It performs many automatic functions such as breathing, heart rate, body temperature, wake and sleep cycles, digestion, sneezing, coughing, vomiting, and swallowing.

Answer 2

Hypothalamus - Pupil

Cerebellum - Muscle coordination

Explanation:

The dilation of the pupil are controlled by the responses from the sympathetic nervous system and the constriction of the pupil is controlled by the parasympathetic nervous system, which are both mediated by the hypothalamus of the brain.

The cerebellum is at the back of the brain, below the cerebrum. It controls balance, movement, and muscle coordination.
