Sensory Receptors
This is a specialized sensory receptor that detects and responds to specific chemical stimuli in the environment or within the body. They detect airborne chemicals and chemicals dissolved in saliva.
Chemoreceptor
The cells in the retina that respond to light stimuli are an example of this specialized receptor.
Photoreceptor
True or False: Neurotransmitters from the gustatory cells can activate sensory neurons in the facial, glossopharyngeal, and vagus cranial nerves.
True!
The initial sensory olfactory neurons are located in this small region within the superior nasal cavity and contains bipolar sensory neurons.
Olfactory mucosa epithelium
This is a specialized sensory neuron that respond to solute concentrations of body fluids and acts as a thirst sensor.
Osmoreceptors
These are tiny "stretch-o-meters" buried inside your muscles, tendons, and joints and they constantly measure how much a muscle is stretched or how much pressure is on a joint and act like your body's internal GPS.
Proprioceptor
These raised bumps contain the structures for gustatory transduction.
Papillae
When _________ bind odorants, a series of intracellular reactions occur that eventually open calcium and/or sodium channels. The resulting ion influx leads to depolarization triggering an action potential of the olfactory neuron that carries the signal into the brain.
Metabotropic chemoreceptors
This sensor only goes off when a stimulus becomes harmful or intense enough to cause tissue damage. Pain is primarily a chemical sense that interprets the presence of chemicals from tissue damage, or similar harmful stimuli, through this sensory receptor.
Nociceptor
This sense provides status reports on your internal organs.
Visceral Sense
This papillae is in the posterior tongue and contain taste buds that sense bitter substance.
Vallate lingual papillae
The axon of an olfactory neuron extends from the basal surface of the epithelium, through an olfactory foramen in the cribriform plate of the ethmoid bone, and into the brain. The group of axons called the olfactory tract connect to the __________ on the ventral surface of the frontal lobe.
Olfactory bulb
Physical stimuli, such as pressure and vibration, as well as the sensation of sound and body position (balance), are interpreted through this sensory receptor.
Mechanoreceptor
This is a sense that has its own dedicated organ and a specific cranial nerve to carry its messages to the brain and there are 5 of them (also name the 5).
Special Sense:
This papillae is on the superficial surface and have taste buds sensitive to sweet tastes.
Fungiform lingual papillae
There is an intimate connection between the olfactory system and the ________ which is one reason why smell can be a potent trigger of memories and emotion.
Cerebral cortex
The physical stimulus that senses temperature and it's channels are ionotropic.
Thermoreceptor
This is the collection of all the information your brain receives from your skin, muscles, and joints, and where touch can be detected as light pressure, deep pressure, vibration, itch, pain, temperature, or hair movement.
Somatosensation
This papillae along the lateral edges are packed with taste buds that pick up sour and salty gustation.
Foliate lingual papillae
True or false: The nasal epithelium, including the olfactory cells, can be harmed by airborne toxic chemicals. Therefore, the olfactory neurons are regularly replaced within the nasal epithelium, after which the axons of the new neurons must find their appropriate connections in the olfactory bulb.
True!
