What else can I help you with?
A group of many nerves that extend down the back is called?
The group of nerves that extend down the back is called the spinal nerves. These nerves originate from the spinal cord and control sensation and movement in different parts of the body.
The posterior rami of the spinal nerves serve what?
skeletal muscles
What includes 12 pair of cranial nerves that extend from the brain and 31 pairs of spinal nerves extending from the spinal cord?
Peripheral nervous system
What innervates the skin and muscles of the back in spinal nerves?
dorsal ramus
What nerves exit from between the spinal vertebrae and extend to various parts of the body?
Peripheral
The dorsal rami of the spinal nerves serves?
Skin and deep muscles of the back.
Muscles of the neck and shoulder are innervated by spinal nerves from what region?
Cervical region
What are the two pathways by which messages are transmitted?
1 sensory organ - sensory nerves - spinal cord - brain 2 brain - motor nerves - spinal cord - muscles
What is the nerves that carry activating impulses to the muscles of inspiration?
The nerves that carry activating impulses to the muscles of inspiration are primarily the phrenic nerves. These nerves originate from the cervical spinal cord (C3-C5) and innervate the diaphragm, the primary muscle of respiration. Additionally, the intercostal nerves, which arise from the thoracic spinal nerves, stimulate the intercostal muscles that assist in expanding the thoracic cavity during inhalation. Together, these nerves coordinate the process of breathing.
Who is attached directly to the spinal cord and what are their job?
The spinal cord is directly attached to the spinal nerves, which emerge from the spinal cord and extend to various parts of the body. These nerves serve as crucial pathways for transmitting sensory information from the body to the brain and motor commands from the brain to the muscles. Additionally, the spinal cord itself is encased in the vertebral column and protected by cerebrospinal fluid, playing a vital role in reflex actions and coordination of movement.
Is the spinal cord the largest bone?
The spinal cord is not a bone, it is a collection on nerves connecting the muscles of most of the body to the brain
What is the correct sequence of nerves that exit the spinal cord?
cervical spinal nerves, thoracic spinal nerves, lumbar spinal nerves, sacral spinal nerves
