Answer:

HOW DO THEY WORK TOGETHER?

Brain and skull-Protecting the central nervous system

The skull and the meninges — the lining of the brain — protect the brain, while the bones of the spinal column protect the spinal cord, and cerebrospinal fluid surrounds and cushions both the brain

and the spinal cord.

Brain and muscles-Receptors in muscles provide the brain with information about body position and movement. The brain controls the contraction of skeletal muscle. The nervous system regulates the speed at which food moves through the digestive tract.

Brain and heart-The brain controls the heart directly through the sympathetic and parasympathetic branches of the autonomic nervous system, which consists of multi-synaptic pathways from myocardial cells back to peripheral ganglionic neurons and further to central preganglionic and premotor neurons.

ORGAN SYSTEM INVOLVED

Brain and skull-The brain and the spinal cord are the central nervous system. The nerves that go through the whole body make up the peripheral nervous system.

Brain and muscles-The nervous system controls various organs of the body directly. The brain also receives information from many organs of the body and adjusts signals to these organs to maintain proper functioning. The skeletal system makes up the framework of the body and allows us to move when our muscles contract.

Brain and heart-The Brain and Nervous System

This portion of the brain stem is located just above the spinal cord. It regulates vital functions, such as heartbeat and breathing
