Neurons in the retina exit the eye forming the what?
Neurons in the retina exit the eye forming the optic nerve.
Do some neurons lack an axon and communicate only with adjacent neurons?
If they are neurons they have an axon, some cell types do communicate using gap-junctions. Yes, some complex sensory organs ( in the retina and organ of Corti for example) do not have axons. These cells liberate transmitter from their soma directly onto postsynaptic neurons in proportion to the membrane potential change they experience.
How many neurons are there in your eyes?
The human retina, which is part of the eye, contains approximately 100 million photoreceptor cells (rods and cones) and several other types of neurons, including bipolar cells and ganglion cells. In total, the retina has around 1 to 1.5 million ganglion cells, which send visual information to the brain. While the exact number of neurons in the entire eye varies, it's estimated that there are several million neurons involved in processing visual information.
What neurons have exactly two projections from the cell body?
Bipolar neurons have exactly two projections from the cell body: one axon and one dendrite. These neurons are commonly found in sensory systems such as the retina of the eye and the olfactory system in the nose.
What are the three types of neurons based on the organization of their processes?
The three types of neurons based on the organization of their processes are unipolar, bipolar, and multipolar neurons. Unipolar neurons have a single process that extends from the cell body, typically functioning as sensory neurons. Bipolar neurons possess two processes, one axon and one dendrite, and are often found in sensory systems like the retina. Multipolar neurons, the most common type, have multiple dendrites and one axon, primarily serving as motor neurons and interneurons in the central nervous system.
Neurons in the retina exit the eye forming the what?
Neurons in the retina exit the eye forming the optic nerve.
Where do we find bipolar neurons?
Bipolar neurons are found in the retina and olfactory nerve in the nose.
The layer of photoreceptors and neurons at the back of the eye is called the?
retina
What Neurons in the retina exit the eye forming the?
optic nerve peace.love.faith
Neurons in the retina exit the eye forming the?
A+ students: the answer is optic nerve.
Bipolar neuron are commonly?
Bipolar neurons are found in the retina and olfactory nerve in the nose.
Where are bipolar neurons found?
Bipolar neurons are primarily found in specialized sensory organs, such as in the retina of the eye and in the olfactory epithelium of the nose. They are responsible for carrying sensory information from these organs to the central nervous system.
What type of stimulus is more important causing action potential give reasons?
It depends on the neuron. Some neurons respond better to a pressure stimulus or temperature, light, sound ect. For example the neurons in the retina of the eye, they respond to photons of light, but do not respond to pressure or sound.
What is the exit point of neurons from the retina of the eyeball has no rods or cones What is this exit point called?
The blind spot
What organs are needed in the nervous system?
The brain, spinal cord, retina, sensory neurons, ganglia, and the nerves
