Chapter 6 Anatomy Flashcards
Anatomy
The study of structures of the human body that can be seen with the naked eye
Physiology
The study of the body’s functions and activities
Histology/ microscopic anatomy
The study of tiny structures found in living tissue
Cells
The basic unit of all living things
Protoplasm
Colorless, jelly like substance in which food elements such as proteins, fats, carbohydrates, mineral salts, and water are present
Organelle
Small organ
Nucleus
The center of the cell
Nucleoplasm
Fluid that contains proteins and DNA (very important acid)
Deoxyribonucleic acid (DNA)
Used to determine our genetic makeup
Cytoplasm
Watery fluid containing food material necessary for cell growth, reproduction, and self repair
Cell membrane
Allows substances to enter and leave the cell
Mitosis
Process of cell reproduction in human tissues that occurs when the cell divides into two identical cells (daughter cells)
Metabolism
A chemical process that takes place in living organisms. This process allows cells to be nourished and carry out their activities
Anabolism
Phase of metabolism: Process of building up larger molecules from smaller ones
Catabolism
A phase of metabolism where complex compounds within the cells are broken down into smaller ones
Tissue
A group of similar cells that perform a certain function
Connective tissue
Supports, protects, and binds together other tissues of the body
