What type of nerves are spinal nerves Are they Afferent Efferent or Mixed?
Spinal nerves are mixed nerves, meaning they contain both afferent (sensory) and efferent (motor) nerve fibers. This allows them to transmit both sensory information from the body to the central nervous system and motor commands from the central nervous system to the body.
What is mixed neuron?
A mixed neuron is a type of nerve cell that contains both sensory and motor functions within a single cell body. These neurons are found in the peripheral nervous system and can transmit both sensory information from the body to the brain and motor signals from the brain to the muscles.
Fiber type in anterior ramus?
alpha spinal motor neuron axons leave the spinal column and enter the nerves via the ventral rami.
What is a motor nerve?
A motor nerve sends an impulse to certain muscles cells to make them contract. The group of muscle cells and the nerve is called a motor unit. Another Answer: In the field of anatomy and physiology, motor nerves are the ones that transmit impulses, called action potentials, from the central nervous system (brain and spinal cord) to skeletal muscles. Sometimes motor nerves send messages that are voluntary or reflexive in order to make muscles contradict or inhibit muscle contraction.Answer A motor nerve is a kind of nerve that carries impulses from the central nervous system that trigger muscles to contract. It also allow to the brain to stimulate muscle contraction. Motor nerve is also called an efferent nerve that exclusively contains the axons of somatic and branchial motoneurons.
What type of nerve sends messages from sense organs to the brain?
Sensory nerves, also known as afferent nerves, transmit messages from sense organs to the brain. These nerves are responsible for carrying information about sensations such as touch, temperature, pain, and proprioception to the central nervous system for processing.

What is the nerve cells type of cells job?
it nerves around
What type of nevers are found in the arm and hand?
There are three main nerves found in the arm and hand: the ulnar nerve, median nerve, and radial nerve. The ulnar nerve supplies sensation to the pinky and part of the ring finger, the median nerve supplies sensation to the thumb, index, middle, and half of the ring finger, and the radial nerve supplies sensation to the back of the hand and thumb.
What type of nerve cells receives stimuli for the sense of small?
Olfactory nerves, definetly. We're studying this currently in my grade.
What is neuralgia?
Neuralgia is a sharp pain that affects nerves, whether it be individual nerves or a group of nerves. Neuralgia is a special type of pain in that it occurs without the stimulation of a pain receptor. How does the pain occur? When the nerve or nerves it's affecting are irritated or damaged.
What is the type of canal that runs through bone and contains blood vessels and nerves?
a nutrient foramen
Can the nervous system repair its cables?
The nervous system is comprised of nerves called neurons, not 'cables'. Different nerve cells can reproduce to create newer nerve cells to replace damaged cells.
Do nerves send messages to the brain at 360 km?
No, nerves do not send messages to the brain at a speed of 360 km. The speed at which nerve signals travel in the body is typically around 100 meters per second, varying depending on the type of nerve and other factors.
Fiber type in anterior ramus?
alpha spinal motor neuron axons leave the spinal column and enter the nerves via the ventral rami.
What part of the body does nerve entrapment affect?
refer to a particular type of pinched nerve, in which peripheral nerves are chronically compressed resulting in pain or loss of function in an extremity. The most common nerve entrapment syndromes affect the median, ulnar and radial nerves of the arms.
What are the different types of neuritis?
Neuritis is inflammation of a nerve. There are different types of neuritis such as optic neuritis (affecting the optic nerve), cranial neuritis (involving the cranial nerves), and peripheral neuritis (affecting peripheral nerves outside the brain and spinal cord). Each type can have various causes and symptoms.
