GENERAL HISTOLOGY

Detailed explanation-1: -Accessory structures of the skin include the hair, nails, sweat glands and sebaceous glands. These structures embryologically originate from the epidermis and are often termed “appendages”; they can extend down through the dermis into the hypodermis.

Detailed explanation-2: -The integumentary system is an organ system consisting of the skin, hair, nails, and exocrine glands. It functions to waterproof, cushion, and protect the deeper tissues, excrete wastes, and regulate temperature, and is interspersed with sensory receptors to detect pain, sensation, pressure, and temperature.

Detailed explanation-3: -Glands: Four types of glands make up integumentary system parts: sudoriferous, sebaceous, ceruminous, and mammary glands. Sudoriferous glands produce sweat and genital secretions. Ceruminous glands produce ear wax. Sebaceous glands produce an oily substance called sebum.
