Question

1. actions controlled by spinal cord ?
2. how the is protected?

Answer 1

Hello Mate,
1.spinal cord functions primarily in the transmission of nerve signals from the motor cortex to the body, and from the afferent fibers of the sensory neurons to the sensory cortex. It is also a center for coordinating many reflexes and contains reflex arcs that can independently control reflexes...

2.The brain stem connects the brain with the spinal cord. It controls hunger and thirst and some of the most basic body functions, such as body temperature, blood pressure, and breathing. The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges.

Answer 2

The spinal cord is made up of bundles of nerve fibers. It runs down from the brain through a canal in the center of the bones of the spine. These bones protect the spinal cord. Like the brain, the spinal cord is covered by the meninges and cushioned by cerebrospinal fluid

Motor Functions - directs your body’s voluntary muscle movements.

Sensory Functions – monitors sensation of touch, pressure, temperature and pain.

Autonomic Functions – regulates digestion, urination, body temperature, heart rate, and dilation/contraction of blood vessels (blood pressure).
