Cells and Body Tissues

Flashcards based on lecture notes about cells and body tissues.

Cytoplasm

Contains nutrients necessary for growth, reproduction, and repair.

Lysosomes

Organelles containing enzymes.

Mitochondrion

Provides the energy for cellular activity.

Nucleus

Is the control center of the cell.

Endoplasmic reticulum

Helps to transport materials through the cell; rough reticulum is the site of attachment for ribosomes, smooth reticulum is the site of fat production.

Ribosomes

Small, granular structures that play a key role in the assembly of proteins.

Golgi Body

Organelle responsible for the modification and transport of proteins.

Tissue

Cells that join together and carry out the same function for the body.

Epithelial tissue

Lines both the inner and outer surfaces of the body and prevents wear and tear.

Nervous tissue

Tissue made up of neurons, which are nerve cells, and passes impulses around the body.

Muscle tissue

Long and thin tissues that produce movement when they contract.

Connective tissue

Connects other types of tissue together.

Simple epithelium

Usually functions as a covering or lining for organs and vessels.

Compound epithelium

Provides external protection and internal elasticity.

Simple epithelium

Consists of a single layer of cells attached to a basement membrane.
