Principal glands of the skin
Sweat glands and Sebaceous glands
Gland that releases water to cool the body
Sweat glands
Gland that secrete oil substances to lubricate hair and skin
Sebaceous glands
Detect pain, touch, heat and cold
Sensory receptors
Sensory receptors that detects very light pressure
Merkel cells
Sensitive to touch and found in delicate areas
Meissner’s corpuscle
Sensory receptors that detects pressure
Paccinian corpuscle
Detects heat and cold
Free nerve endings
- framework of the body
- bones and connective tissue
- protect the organs
