Question

The spinal cord relays messages between the body and the brain. These messages control body functions like movement, bladder and bowel control and breathing. Each vertebra has a pair of spinal nerves that receive messages from the body (sensory impulses) and send messages to the body (motor impulses). The spinal nerves are numbered 1 to 55 from the neck down. The first eight as seen here are the vertebrate and send messages to the back of the head, neck, shoulders, arms, hands and diaphragm. A) cervical B) lumbar C) sacral D) thoracic​

Answer 1

The correct answer to the student's question regarding the spinal nerves numbered 1 to 8, which control functions for the back of the head, neck, and upper limbs, including the diaphragm, is A) cervical.

Step-by-step explanation:

The spinal cord is a crucial part of the nervous system, functioning as an information superhighway between the brain and the rest of the body. It consists of 31 spinal nerves, each containing sensory and motor axons. The cervical nerves, numbered 1 to 8, correspond to the question's description and are responsible for sending messages to the back of the head, neck, shoulders, arms, hands, and diaphragm.
