The cell is the basic structural and functional unit of all living organisms.
Histology is the study of the microscopic structure of tissues.
Epithelial, connective, muscle, and nervous tissues.
The integumentary system includes the skin, hair, nails, and associated glands.
Protection against environmental hazards, temperature regulation, and sensory reception.
The microscope is essential for viewing cells and tissues at a microscopic level.
An organ system is a group of organs that work together to perform complex functions.
The integumentary system is an example of an organ system.
Epithelial tissue covers body surfaces and lines cavities, providing protection and absorption.
Connective tissue supports, binds, and protects other tissues and organs.
Muscle tissue enables movement through contraction.
Nervous tissue transmits electrical signals to coordinate body functions.
It allows visualization of cells and tissues too small to be seen with the naked eye.
The epidermis, dermis, and hypodermis (subcutaneous layer).
The epidermis is mainly composed of keratinized stratified squamous epithelial cells.
The dermis provides strength and elasticity and contains blood vessels and nerves.
The hypodermis is made of loose connective tissue and fat, providing insulation and cushioning.
Cells form tissues, tissues form organs, and organs work together in organ systems.
Anatomy studies structure, while physiology studies function; together they explain how the body works.
Glands produce sweat and oils to regulate temperature and protect the skin.
