What are the colors of your nervous system?
Nervous tissue does not have a specific color as it is made up of cells, fibers, and blood vessels. However, nerve tissue can appear white due to the myelin sheath that surrounds certain nerve fibers.
Where does the optic nerve enter the eye?
The optic nerve enters the eye at the back of the eyeball through an opening called the optic disc. This area is also known as the blind spot because it lacks light-sensitive cells (rods and cones) that are present in other parts of the retina.
Sounds entering the external auditory canal are eventually converted to nerve impulses via a chain of events?
Yes, sound waves travel through the external auditory canal and cause the eardrum to vibrate. These vibrations are then transmitted through the middle ear bones to the inner ear, where they stimulate hair cells in the cochlea. The hair cells convert the vibrations into electrical signals that are sent to the brain via the auditory nerve.
What tissuse are in the hypothalamus?
The hypothalamus contains various types of tissue including nervous tissue, particularly nerve cell bodies and nerve fibers, as well as glial cells that provide support and protection for the neurons. Additionally, the hypothalamus contains blood vessels that supply nutrients and oxygen to the tissue, allowing it to function properly.
The phrenic nerve arises from the?
The phrenic nerve arises from the spinal cord at C3, C4, and C5 nerve levels. It originates from the cervical plexus and innervates the diaphragm muscle, playing a crucial role in controlling breathing.
What is the difference between nerve cells and nerve?
a nerve tends to refer to a group of nerve cells.
What is the name of a group of nerve cells?
A group of nerve cells or neurons is called ganglia.
What is a group of nerve cells called?
A group of nerve cells is called a "neuron" or "nerve cell cluster". These cells are fundamental units of the nervous system and work together to transmit electrical and chemical signals throughout the body.
What are a group of nerve cells that act as a primitive brain called?
ganglia
What are pacemaker cells in the human body?
They Are A Special Group Of Nerve Cells. Nerve Signals From The Brain Control The Pacemaker, Making It Go Faster Or Slower When Required. Specialist cells in the heart which have autorhythmicity.
What is a connector nerve?
Connector nerve cells connect the sensory nerve cells with motor nerve cells and allow for decision making.
What nerve cells that connect sensory and motor nerve cells?
It depends upon what you are referring to as connecting. Most nerve cells do not connect to each other, but pass their impulse from one to the other via synapses. There are also places where nerve cell bodies cluster together in the peripheral nervous system, and this is known as a ganglion. When a group of nerves come close to each other and are covered in connective tissue for protection, it is called a plexus. The nerve do not actually connect to each other, but are wrapped together.
What type of nerve is the optic nerve?
ganglion cells
Do dogs have nerve cells?
Yes, dogs do have nerve cells.
What are neural cells?
A nerve cell is the structural and functional unit of a nerve
Does the peripheral nervous system have sensory nerve cells and motor nerve cells?
False
Are the cells that transmit sensory message called nerve cells or muscle cells?
Nerve Cells. 100% sure.
