Question

identify the structures in the diagram above.
dermis
sebaceous gland
sweat gland duct
touch/pressure receptor
arrector pili muscle

Explanation:

1. Dermis: This is the middle layer of skin, labeled as region B between the epidermis (A) and hypodermis (C).
2. Sebaceous Gland: This gland is associated with hair follicles, secreting sebum, and is labeled M.
3. Sweat Gland Duct: This structure carries sweat from the gland to the skin surface, labeled K.
4. Touch/Pressure Receptor: This sensory receptor (Meissner's or Pacinian corpuscle, here labeled J) detects tactile stimuli.
5. Arrector Pili Muscle: This muscle attaches to hair follicles, causing hair to stand, labeled N.

Answer:

• Dermis: B
• Sebaceous Gland: M
• Sweat Gland Duct: K
• Touch/Pressure Receptor: J
• Arrector Pili Muscle: N
