What is olfactory neurons?
They process and relay sensory input from your nose.
Where are olfactory receptors located?
In vertebrates the olfactory receptors are located in the cilia of the olfactory sensory neurons. In insects olfactory receptors are located on the antennae and other chemo sensory organs.
Sensory neurons of the PNS are?
Unipolar Sensory Neurons: large myelinated neurons with the cell body off to one side of the single dendritic-axon process. Multipolar Motor Neurons: large myelinated neurons that have many dendrites off the cell body and an axon that may branch to effect many effectors.
What is in charge of your olfactory system?
The mechanism of the olfactory system can be divided into a peripheral one, sensing an external stimulus and encoding it as an electric signal in neurons, and a central one, where all signals are integrated and processed in the central nervous system. The peripheral olfactory system receptors are connected to bipolar olfactory receptor neurons in the olfactory epithelium. Fot the central olfactory system, axons from the olfactory sensory neurons converge in the olfactory bulb.
Myelinated neurons are embedded in what?
the axons of myelinated neurons are embeded in a protective covering of gray matter.
What are neurons called that detect stimuli in the skin and eye?
sensory neurons
Sensory neorons and neurons are connected by-?
Sensory neurons and neurons are connected by Interneurons.
Do action potential transmission is faster in myelinated neurons?
TRUE. Neurons with myelin (or myelinated neurons) conduct impulses much faster than those without myelin.
Are neurons that relay impulses from sensory neurons to motor neurons?
Sensory Neurons
What are neurons that relay impulses from sensory to motor neurons?
Sensory Neurons
Which neuron is never myelinated?
Neurons that do not have a myelin sheath must use continuous conduction, which is slower. These are the smaller axons of the CNS, as well as some types of fine sensory fibers, such as olfactory nerves.
Where is the olfactory epithelium found?
The olfactory epithelium occupies an area of about 5 cm2 in the roof of the nasal cavity. The specialized receptor cells in the olfactory epithelium are surrounded by supporting cells, non-sensory epithelial cells. The olfactory receptor cells are bipolar neurons whose olfactory cilia extend outward from the epithelium.
