The sensory receptors are the nerves which are stimulated by a physical stimulus and create nerve impulse to send information to the brain. The tactile receptors are the most numerous types of sensory receptors. These receptors are present in the skin and mucous membranes. The dendritic nerve endings of tactile receptors are either unencapsulated or encapsulated.

Question

Chapter 16, Problem 1DYB

Summary Introduction

Concept introduction: The sensory receptors are the nerves which are stimulated by a physical stimulus and create nerve impulse to send information to the brain. The tactile receptors are the most numerous types of sensory receptors. These receptors are present in the skin and mucous membranes. The dendritic nerve endings of tactile receptors are either unencapsulated or encapsulated.

Expert Solution & Answer

Answer to Problem 1DYB

Correct answer: Unencapsulated dendritic endings of sensory neurons are called free nerve endings.

Therefore, option b. is correct.

Explanation of Solution

Reason for the correct answer:

Option b. is given as “free nerve endings”.

The free nerve endings are the apex of any tactile sensory receptor and are not covered by any protective layer on their end. These receptors are found closest to the skin surface and mucus membrane. The free nerve endings are sensitive to pain and temperature stimuli.

Hence, option b. is correct.

Reasons for incorrect answers:

Option a. is given as “lamellated corpuscles”.

The lamellated corpuscles are covered by the connective tissue and specialized glial cells. They are located at the reticular layer of the dermis, soles of the feet, breasts, and the external ganglia as well as walls of the some organs. Hence, option a. is incorrect.

Option c. is given as “bulbous corpuscles”.

These nerve endings are also known as ruffini endings. These receptors are found in cutaneous tissues. These are spindle shaped neurons and have a covering layer. Hence, option c. is incorrect.

Option d. is given as “end bulbs”.

These are rounded or oval structures located at the dermis, mucous membranes of the nasal cavity, oral cavity, vagina, and the anal canal. These receptors are covered by the connective tissue and specialized glial cells. Hence, option d. is incorrect.

Hence, options a., c., and d. are incorrect.

Conclusion

Free nerve endings are the receptors that are unencapsulated.

Students have asked these similar questions

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
