2024 BIOD 152 - Portage Learning Anatomy and Physiology Module 1-7 Exam With Answers (139 Solved Questions) - Page 3 preview imageStimulation of olfactory receptors has a great effect on the sensation of taste inaddition to taste bud stimulation. When the olfactory receptors are obstructed bynasal congestion or other factors, the sensation of taste is dulled or completelylost. Other factors, such as TBI or a brain tumor inside the brain, can also causeageusia if the taste pathway is damaged.Special Senses - The 5 senses that have specialized organs containing specializedreceptor cells, which carry their impulses by way of specialized somatic andvisceral afferents.(Vision, smell, taste, hearing, and equilibrium)Which of the senses is not a special sense? - TouchInstead of having a specialized sense organ, touch uses general receptorscomposed of modified dendrites of sensory neurons.What does touch include? - Pressure, vibration, pain, heat, and the combinedinformation is carried in general somatic afferents and general visceral afferents.How many layers consist of the organ that is responsible for sight? - The eyeconsists of 3 layersWhat does the outer fibrous layer of the eye include? - Sclera and corneaSclera - The posterior portion of the outer layer of the eye; AKA the white of theeye.

It is highly vascular andsupplies blood to the other layers of the eye.What part of the eye supplies blood to the other layers? - ChoroidCiliary Body - Anterior to the choroid in the middle layer of the eye; changes theshape of the lens, allowing it to focus.Iris - Anterior to the ciliary body in the middle layer of the eye; contains thecircular colored portion of the eye. It controls the amount of light let into the pupiland uses its muscle fibers to contract or dilate based on the amount of light in theenvironment.Pupil - A hole in the center of the iris.How does the iris control the amount of light let into the pupil? - The iris uses itsmuscle fibers to contract or dilate based on the amount of light in theenvironment.What is the inner sensory layer of the eye? - Retina
