What does spinal column protect?
The spinal column, a series of vertebrae composed of bone, protects a part of the nervous system known as the spinal cord. The spinal cord is a bundle of nerves that helps to carry messages to various parts of the body.
What organs in vertebral cavity?
Spinal cavity is one of the cavities in human body. It is a space between vertebrae through which spinal chord passes. It is also known as spinal canal or vertebral canal.
How do somatic sensory nerve impulses get to the brainstem from the head itself?
Somatic sensory nerve impulses get to the brainstem from the head itself via the cranial nerves. Cranial nerves are also known as cerebral nerves.
What is efferent nerves?
efferent signals are those sent out from your CNS instructing some part of your body to act a certain way.
The optic nerves from the eyes cross before entering the brain the crossed structure is known as?
optic chiasm?
What are the nerves outside the brain and spinal cord?
The peripheral nervous system contains all the nerves in the body that lie outside of the spinal cord and brain.They communicate with the central nervous system to make sure our body parts, such as our fingers, can send signals to the central nervous system for processing in our brains.
What is made of brain nerves and spinal cord?
Nervous system
What does spinal column protect?

Which among the frog's spinal nerves is the largest?
YES. Frogs do have spinal cords.
Does the nerve going to the eyebrow go to the spinal cord?
There are 31 pairs of spinal nerves which originate in the spinal cord. There are twelve cranial nerves, which are referred to by Roman numerals. Ten of the twelve cranial nerves originate from the brainstem; the other two stem from the forebrain and thalamus. The nerve that is responsible for eyebrow movement is the VII cranial nerve, also known as the facial nerve. This is one of the ten cranial nerves originating from the brainstem.
What system of body is made of brain the spinal cord and the nerves?
The system of the body is made of the brain spinal cord and nerves is known as the nervous system. The nervous system controls the body's voluntary and involuntary actions and transmits signals between different parts of its body.

What body cavity is the cerebellum in?
The cerebellum is in the cranial cavity. The dorsal body cavity is also known as the cavity that encloses the brain and the spinal cord but the brain is protected from trauma by the cranial cavity.
What does foraminotomies mean?
Foraminotomies are surgical procedures aimed at widening the passageways where nerves exit the spinal column, known as the foramina, in order to relieve pressure on compressed nerves. This can help alleviate symptoms such as pain, numbness, or weakness caused by conditions like herniated discs or bone spurs.
In black death what colour was the fluid that would come out of the swellings?
The Black Death is also known as the bubonic plague. The swellings are black in color. The fluid is yellow with a bloody tinge.
Why are most spinal cord or nerve tissue injuries permanent?
Nerve tissue mass and spinal fluid are unable to replicate. Spinal cord injury is damage to the spinal cord that causes loss of sensation (feeling) and motor (muscular) control. There are approximately 250,000 people in the USA who currently have spinal cord injuries and a further 10,000 accidents to the spinal cord occur each year! An injury to the Spinal cord can happen to anyone at any time of life. The typical patient, however, is a man between the ages of nineteen and twenty-six. The most common causes of a Spinal Cord Injury are motor vehicle accidents (which are responsible for 50 percent of all cases), a fall (20 percent), an act of violence (15 percent), or a sporting accident (14 percent). Alcohol or drug abuse is involved in many of the accidents that result in spinal cord injuries. About 6 percent of those who suffer injury to the lower spine die within a year while approximately 40 percent of those who suffer injury to the upper spine die within a year. The spinal cord is a long rope-like piece of nervous tissue. It runs from the brain down the back. It is contained within the spinal column. The spinal column consists of a set of bones known as vertebrae. Pairs of nerves travel from the spinal cord to muscles in the arms, legs, and other parts of the body. Messages travel from muscles to the spinal cord and then to the brain along one set of nerves. Messages travel in the opposite direction, from brain to spine to muscles, along the other set of nerves. Each pair of nerves is connected to the spinal cord in the space between two adjacent vertebrae. The nerves are named for the vertebrae where they enter the spinal cord. The five sets of nerves connecting to the spinal cord are defined as follows: * C1-8 nerves enter the spine near the eighth cervical vertebrae, located in the neck. * T1-12 nerves enter the spine near the thoracic vertebrae, located in the chest. * L1-5 nerves enter the spine near the lumbar vertebrae, in the lower back. * S1-5 nerves enter the spine through the sacral vertebrae, located in the pelvis region. * The coccygeal nerves (pronounced kock-SIHJ-ee-uhl) enter the spine through the coccyx, or tailbone. Injury to the spinal cord may damage any one or more of these nerves. When nerves are damaged, messages can not travel from the brain to the body's muscles, or from the muscles to the brain. For example, a person may lose their sense of touch if nerve messages are not able to travel from the fingers to the brain. Or a person may lose the ability to walk if nerve messages can not travel from the brain to leg and foot muscles. Other functions, such as urination, sexual function, sweating, and blood pressure, may also be affected. Further information is on the link provided :)
