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.
10 of the 12 pairs of cranial nerves originate from the?
Brainstem (midbrain, pons, and medulla).
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.
Which part of the brain is spplied by nerves?
The brainstem has nerves which extend outward to supply structures located mostly in the head and neck. These are called the cranial nerves.
Pure sensory cranial nerve?
Cranial nerves are primarily sensory. These nerves are directly between the brain and the brainstem and are responsible for smell, vision, eye movement, facial sensation, and the tongue movement.
Peripheral nerves arise from the?
either the brain or the spine Correction: 2 from the forebrain (olfactory 1, and optic 2) 10 from the brainstem (cranial nerves 3 - 12)
How long is the brainstem?
The brain stem is relatively short, around 7-centimeters long. The brainstem provides the main motor and sensory innervation to the face and neck via the cranial nerves.
Where the cranial nerves belong?
Cranial Nerves 1-2 Cranial Nerves 3-4 belong to the midbrain. Cranial Nerves 5-8 belong to the pons. Cranial Nerves 9-12 belong to the hindbrain.
How many cranial nerves are?
How many cranial nerves are there
What are the organs of smell and the cranial nerves connected to them?
The organ of smell is the nose - more specifically it is a patch of epithelium called the olfactory epithelium located in the roof of the nasal cavity. The cranial nerves associated with smell are the olfactory (I) nerves
Why are cranial nerves known as cranial neveres not branial nerves?
Because somebody would ask why it wasn't cranial nerves instead of brainial nerves.
Are Cranial nerves paired?
yes! there are 12 pairs of cranial nerves
