Verified step by step guidance

Understand the concept of nonencapsulated (free) nerve endings: These are sensory nerve endings that are not enclosed in a capsule and are typically found in the skin and mucous membranes. They are responsible for detecting pain, temperature, and light touch.

Identify the characteristics of each option: Lamellar (Pacinian) corpuscles, tactile (Meissner's) corpuscles, muscle spindles, and hair follicle receptors.

Lamellar (Pacinian) corpuscles: These are encapsulated nerve endings that detect deep pressure and vibration. They are not free nerve endings.

Tactile (Meissner's) corpuscles: These are also encapsulated and are responsible for detecting light touch and texture. They are not free nerve endings.

Hair follicle receptors: These are nonencapsulated nerve endings that wrap around hair follicles and detect hair movement, making them the correct answer.
