Almost all nerves have to pass through some sort of opening. In this case, they are called foramina.

Where do axons from the olfactory nerve project to?
Axons from the olfactory nerve project directly to the
What is the pathway of smell from the olfactory receptors to the brain?
The olfactory bulb is a small , match-head sized organ in the top of the nasal cavity,and is connected to hundreds of olfactory hairs, or cilia, which lie in a layer of mucous. These have receptor sites, and it is still not well understood how these work, but one theory is that the shape of the molecule (of the substance being smelt) and the way in which it locks onto the receptor determines the impulses sent to the brain. (the bulb is thought of as a direct extension of the brain) If this is true, it may help explain why with prolonged exposure to a smell, you will stop smelling it until you go outside and clear the nose and come back.The receptor sites become saturated with the molcules and stop sending nerve impulses.
What happens when you stimulate an axon in the middle?
Axons have no receptors for stimuli, only the dendrites off of the soma are capable of having receptors for different stimuli
What is a group of axons bundled together coated in myelin that travels together through the body called?
Its called a tract; while a bundle of axons in the PNS is called a nerve
Can oligodendrocytes myelinate several axons?
yes TRUE
What passes through cribiform plate?
Small unmyelinated axons from olfactory receptor bipolar neurons (originating in the olfactory epithelium of the nasal cavity) pass through small holes in the cribriform plate of the ethmoid bone. These small nerves are primary sensory neurons that synapse with the olfactory bulb of Cranial Nerve 1 (olfactory nerve) which lies on top of the cribriform plate. These olfactory receptor neurons bind to different types of odorant molecules and, depending on the type of receptor and odorant molecule, fire action potentials which are transmitted to the brain and perceived as recognizable odors. Specifically these are called the Fila Olfactoria.

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.
Function of olfactory tract?
The olfactory tract is a bundle of axons connecting the mitral and tufted cells of the olfactory bulb to several target regions in the brain.

What is c type of sensory nerve fibers detail?
C fiber sensory nerves have small diameter unmyelenated axons and carry the signals from pain receptors.
Does the dendrite come first or does the axon come first?
The dendrite. It receives signals, either from sensory receptors or from other neurons, and then passes that signal eventually to axons.
Why do mice stink?
Yes! i have a male mouse But it is not that bad. Just make sure everyonje in the household won't mind. and i suggest this product; it is the one i use to clean his cage: http://www.petsmart.com/product/index.jsp?productId=2753346&cp=&sr=1&origkw=cage+cleaner&kw=cage+cleaner&kwCatId=2767038&parentPage=search&keepsr=1
What areas do the neurotransmitters diffuse through?
Primarily the Brain: from the Axons to the Dendrites.
How do people smell food?
A specialized smell receptor is situated In the roof of the nasal canal,called Olfactory mucosa. the olfactory epithelium is innervated by the olfactory(1st cranial)nerve and some branches of the 5th nerve.Olfactory epithelium contains three kinds of cells,namely olfactory receptor cells,supporting cells and basal cells.Olfactory receptor cells are sensory hair cells,sensitive to all kind of cells.Their axons terminally join the olfactory nerve. Supporting cells are mucus-secreting columnar cells. Basal cells are the stem cells from which new receptor cells are formed.Olfaction,just like taste,is a chemical sense. The molecules of the odorous substances reach the nasal canal along with the inspired air. Here, they dissolve in the mucus secretion and then attach to the receptor cells. This stimulates the receptor cells and they generate olfactory impulses. Olfactory nerves transmit these impulses to the olfactory center in the temporal lobe of the cerebrum(known as the olfactory cortex)
