To label: The somatosensory receptors in Figure 23.1 (a).
Introduction: A cell or a group of cells that is specialized in detecting the changes in the environment and triggers the impulses in the sensory nervous system is referred to as the somatosensory receptors. The somatosensory receptors are categorized into five types, namely the thermoreceptors, mechanoreceptors, pain receptors, proprioceptors, and chemoreceptors.

Answer to Problem 1.1BGL

Explanation of Solution
1. Type I cutaneous mechanoreceptor: They are free nerve endings located in the skin and is associated with the Merkel cells in the stratum basale layer of the epidermis. The stimuli of these receptors are touch and pressure.
2. Corpuscle of touch: They are encapsulated nerve endings situated in the dermal papillae of the hairless skin. Touch and pressure are the stimuli of these receptors.
3. Type II cutaneous mechanoreceptor: They are encapsulated nerve endings that are situated on the tendons, ligaments, and dermis. Stretching of the limbs and digits are the stimuli of these receptors.
4. Root hair plexus: They are the free nerve endings that surround the follicles of hair. The stimuli of root hair plexus touch the hair.
5. Lamellated corpuscle: They are encapsulated nerve endings situated in the subcutaneous and submucosal muscles, tissues, joints, and tendons. Touch and pressure are the stimuli of these receptors.

Explanation of Solution
6. Muscle spindle: They are encapsulated nerve endings located within most of the skeletal muscles. These receptors respond to the changes in the length of the muscles.
7. Tendon organ: They are encapsulated nerve endings situated at the junction of the muscles and tendons. These receptors respond to the changes in the movement and position of the joints.
