Olfactory receptors connect to the ___________ ______ of the first cranial nerve.
Olfactory bulb
_________ is the shell shaped part of the bony labyrinth containing the cochlear duct, and is concerned with hearing.
Cochlea
_______ ________ is part of the __________ bone, in the superior nasal cavity this is covered by a specialized area of nasal mucosa.
Cribiform plate, ethmoid
CN _ or ________ nerve is not considered a true nerve because it is structurally and functionally already part of the CNS.
1, olfactory
_____ _________ are numerous olfactory axons that collectively make up the olfactory nerve.
Fila olfactoria
___________ is phylogenetically the oldest portion of the cortical mantle of the cerebral hemisphere and develops in association with the olfactory system.
Paleocortex
_________ is comprised of the piriform complex and the parahippocampal gyrus and receives sensory info from the MOB and the olfactory tract in the temporal lobe.
Paleocortex
the ________ ________ _______ along with the olfactory tract carries olfactory info to the paleocortex in the temporal lobe along the olfactory stria near the uncus.
Main olfactory bulb
All vertebrates except for aquatic mammals posses a ________ ________ ________.
Main olfactory bulb
The _________ _________ ______ is present in most vertebrates but is absent in OWM, apes and humans and is associated with the VNO.
Accessory olfactory bulb
The _______ _________ _______ is thought to receive sensory input via volatile, airborne stimulus. This is associated with the MOB.
Main olfactory epithelium
the __________ _______ is not functionally separate from the MOE but receives nonvolatile aromatic stimuli called pheromones and uses the AOB.
Vomeronasal organ
A __________ is a nonvolatile aromatic stimulus received by the VN which can cause hormonal responses and in humans are found in apocrine glands, saliva, seminal and vaginal secretions and urine.
Pheromones
The _____ ________ __ ______ is a small area of olfactory epithelium located in the nasal mucosa posterior to the nasopalatine ducts that connect the oral and nasal cavities. This has been identified in rodents, but not in primates.
Septal organ of masera
The _______ _______ ___ ________ is used for alarm/alert pheromone reception in rodents.
Septal organ of masera
The ________ ________ is found in rodents, and is used as maternal and/or alarm pheromone receptors.
Gruenberg ganglion
________ ________ _______ are formed from scroll-like bony features of the maxilla and ethmoidal elements in the internal nose.
Nasal turbinate bones
nasal turbinate bones are also known as _________ _______.
Nasal conchae
___________ unites the nasal turbinate bones with the oral cavity.
Nasopharynx
___________ ______ are within the frontal, ethmoid, sphenoid, and maxillary bones and open into the nasal cavity beneath the turbinate mucosa.
Paranasal sinuses
________ are moist, naked surfaces surrounding the nasal openings/nostrils of most mammals.
Rhinarium
__________ are sensitive to touch but no olfactory receptors, probably assists in delivering pheromone molecules to the VNO and is attached to the mucus membranes of the premaxilla by the philtrum.
Rhinarium
____________ is a taste sensation that responds to glutamic acid.
Umami
____________ is a taste sensation that responds to alkalinity
Bitter
___________ is a taste sensation that responds to acidity
Sour
__________ is a taste sensation that responds to glucose
Sweet
___________ taste sensation works closely with sweetness to assess ripeness
Sour
___________ taste sensation has an inverse relationship between sensitivity and body size
Sweet
Larger people have a lessened sensitivity to sweetness
_____________ taste sensation is limited in concentrated forms in nature. This is important to detect and preference may be learned in humans
Salty
_______________ taste sensation is typically avoided due to the association with toxic secondary compounds, yet secondarily sought after by humans for other side effects
Bitter
____________ is the least understood taste sensation and is used as a flavor enhancer
Umami
Strepsirrhines are _____-______ _________ , this may increase their ability to smell.
Wet-nosed primates
Haplorhines, including platyrrhines and catarrhines, are ___-______ ________.
Dry-nosed primates
