Summary Introduction
To review:
The “survey the landscape” figure which connects each general and special senses to the term “homeostasis” in the pull it together concept map.
Concept introduction:
Homeostasis is the term that can be referred to the stable state of the organism’s body and its internal environment. The homeostatic condition occurs by the regulation and maintenance of the bodily functions. The stability in an internal environment refers to the stability in terms of the body temperature, extracellular and intracellular fluid balance,

Which is true regarding somatotopic organization?
Select one:
a. Certain areas of the body have much higher representation in the primary somatosensory cortex than other areas, and these regions will have finer tactile discrimination.
b. The representation of a given area of the body in the primary somatosensory cortex is directly proportional to the size of that body area (e.g., the right index finger has less representation than the right thigh).
c. The receptive fields for somatosensory neurons are circular and relatively consistent in size across areas of the body, but areas of the body with the finest tactile discrimination have many more neurons representing them in the primary somatosensory cortex.
d. There is equal representation of all areas of the body in the primary somatosensory cortex
Create a visual representation comparing and contrasting the parasympathetic and sympathetic nervous system- including what each system is responsible for, the receptors involved in each system, and what happens when these receptors are stimulated vs. when they are blocked.

Which of the following presents the elements of a sensory system in the correct order?
Select one:
Accessory structure modifies energy and sensory nerves transfer activity to central nervous system, thalamus processes
and relays activity to cerebral cortex, cerebral cortex transfers input to accessory structures and sensation or perception is
produced.
Accessory structure modifies energy, receptor transduces energy into neural activity, sensory nerves transfer activity to
central nervous system, thalamus processes and relays activity to cerebral cortex, cerebral cortex receives input and
produces sensation and perception.

- An example of a sensory neuron is one that leads from a pain receptor in the finger to the spinal cord. A pin can be pressed against the skin without eliciting a response from the pain receptor. However, if the pin is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly withdrawn through a reflex arc. How do we sense different types of pain (very painful vs. not painful at all)? Using what you understand about threshold potentials and the all-or-none principle, explain how it is possible to sense different levels of pain. question is in boldarrow_forwardImagine you wake up to the smell of smoke, The sound of the fire alarm, the flashing lights of sirens, the acreage taste of smoke in the air. In other words, all your senses are reacting to this emergency. Your body goes into "flight or fight mode". Question: in about two paragraphs, can you describe the sensory pathway that the sensory information from just one of these special senses takes to the brain to be integrated. for example, if you were describing the smell of the smoke, how was odor detected? Which cranial nerves are involved? Where are those located? Where do they connect to the rest of the brain?arrow_forwardIn the process of sensory coding Recruitment of additional neurons occurs with a weak stimulus in order to make the stimulus stronger. The larger the receptive field of a sensory receptor, the greater the expected acuity and the more accurate the two-point discrimination. Lateral inhibition of neighboring receptors resulting in a relative reduction of action potentials in the neighboring second order neurons would be expected to increase acuity. A receptor potential that remains suprathreshold into the absolute refractory period will result in additional action potentials.arrow_forward

The mechanisms involved in opponent-process theory take place earlier in the perceptual process than those involved in trichromatic theory. The processes proposed by both trichromatic theory and opponent-process theory take place in the primary visual cortex. Trichromatic theory and opponent-process theory are both strongly supported by behavioral and physiological evidence. Recently, trichromatic theory has overtaken opponent-process theory as the best explanation of color and hue perception.arrow_forwardWhich statement about a center-surround receptive field is false? Select one: a. It can involve an inhibitory response (e.g., to touch) b. It is characterized by a circular center and a doughnut-shaped surround c. It is found only in primary sensory cortex d.

- The brain’s somatosensory cortex does not consist of neurons that receive information equally from all parts of the animal’s body. Describe an example of this by identifying a relevant animal and the body parts that are disproportionately high in neuronal input to the somatosensory cortex.arrow_forwardWhich is True and which is False? The receptors that allow us to sense linear acceleration as our airplane takes off are located in the middle ear. The human sensory homunculus devotes considerable space to the larger parts of the body, such as the torso and legs. Athletes in contact sports like boxing and football readjust their sensitivity to pain, not just their attitudes.arrow_forwardEnvironmental input to different sensory systems affects different neuroanatomical pathways. However, there is a basic, common pathway plan that most sensory systems share.
