answers/sure pass A+
1. A with a Diameter carries electrical impulses
the fastest: Myelinated, Large
2. The finger-like projections extending from the neuron's cell body that are most
frequently the site of stimulation and formation of graded potentials are called: Dendrites
3.Sense
When a stimulus activates its specific sensory receptor. Perceive
The process of your brain interpreting all the stimuli at a given time Receptors can either
Adapt
fast or slowly. If they do so quickly, they are called Tonic
receptors, if they do so slowly, they are called Phasic
receptors.:
4.general senses include: (Consciously )
Consciously perceived:

pain
5. general senses (unconscious): Blood Pressure Blood
composition
Stretching of viscera
Oxygen
pH
6. 5 special senses: Olfaction (smell)
Gustatory (Taste)
Sight
,Auditory (hear)
Equilibrium (Balance)
7. Exteroceptors =: primarily sense stimuli that are coming from the outside. Your special
senses of sight, smell and hearing along with the general somatic senses associated with touch.
Receptors that receive outside stimulus
8. Interoceptor=-: monitor and maintain the homeostatic balance of your body as well as check
for stretching, pressure and damage to internal organs.
receptors located inside, along organs
9. Proprioceptor=: The prefix "Proprio" means self or one's own. It is aptly named since
proprioceptors will communicate to your brain how the body is positioned.
where are you? receptors in muscles, tendons, and joints
10.Exteroceptors
receptors sense information coming from the outside.
Interoceptor
sense information originating from the inside while Proprioceptor
receptors sense information about body position.:
11. Mechanoreceptors (Senses mechanical changes)
Osmoreceptors (Senses body fluid osmolarity)
Thermoreceptors (Sense Changes in temperature)
Chemoreceptors (Sense Chemicals)
Photoreceptors (Senses light) Nociceptors
(Senses Pain):
12. Mechanoreceptors: Mechanoreceptors sense anything that has to do with tactile
sensations. Tactile sensations have many sensory modalities including:
Touch
Pressure
Itch
Tickle
Vibrations
Stretching
Proprioception
13. chemoreceptors: chemical sensors in the brain and blood vessels that identify changing
levels of oxygen and carbon dioxide
14.nocireceptors: pain receptors
, 15.Mechanoreceptors: respond to touch, pressure, vibration, stretch, and itch
16.Photoreceptors: respond to light (rods and cones)
17.osmoreceptor: A sensory receptor that detects changes in water potential
18.thermoreceptor: A receptor that responds to changes in temperature.
19. To is when a stimulus successfully stimulates an action poten- tial
in its specific neuron. How your brain interprets the message is how the stimulus is
.: sense; perceived
20.Any senses categorized as special senses have this in common ;
A) They are all exteroceptors
B) They are the only receptor types located in the head.
C) They all use a type of chemical receptor to sense stimuli
D) All their sensory neurons have specialty cells used for sensing: a
21. are the fast adapting type of
sensory receptors. They sense a stimuli and then shutdown very quickly. are the
slowly adapting receptors. : tonic; phasic
22. The process in which a sensory structure is stimulated and creates a graded
potential in a neuron is called:
Phasic
Perception
Transduction
Sense: Transduction
23. True or False: A single neuron and its receptor can sense multiple stimulus types.
True False:
false
24. True or False: Receptors for Pressure and stretch are only exteroreceptors. True
False: False
25. What type of sense is touch considered?
Special Sense
General Sense: general
26. The tactile sensations is a combination of five different sensory modalities. They
are:: Touch
Pressure
Vibration
Itch
Tickle
27. where is the location of the free nerve ending?: The location of free nerve ending
receptors are associated with the epidermal layer of the skin.
