Cell Membrane
Structure surrounding and protecting the cell. It determines what enters and leaves the cell.
Chromosomes
Rod-shaped structures in the nucleus that contain regions of DNA called genes.
Cytoplasm
All the material that is outside the nucleus and yet contained within the cell membrane.
DNA
Chemical found within each chromosome. Arranged like a sequence of recipes in a code, it directs the activities of a cell.
Endoplasmic Reticulum
Network of canals within the cytoplasm of the cell. Here, large proteins are made from smaller pieces.
Genes
Regions of DNA within each chromosome.
Karyotype
Picture of chromosomes in the nucleus of a cell. The chromosomes are arranged in numerical order to determine their number and structure.
Metabolism
Total of the chemical processes in a cell. It includes catabolism and anabolism.
Meta
Change
Mitochondria
Structures in the cytoplasm that provide the principal source of energy for the cell.
Nucleus
Control center of the cell. It contains chromosomes and directs the activities of the cell.
Adipose Tissue
Collection of fat cells
Cartilage
Flexible connective tissue often attached to bones at joints.
Epithelial Cells
Skin cells that cover the outside of the body and line the internal surfaces of organs.

Pharynx
Throat. The pharynx serves as a common passageway for food (from the mouth going to the esophagus) and air (from the nose to the trachea).

Thyroid Gland
Endocrine gland that surrounds the trachea in the neck
Trachea

Urethra
Tube from the urinary bladder to the outside of the body
Uterus

Pertaining to the back
Mediastinum
Centrally located space outside of and between the lungs
Pelvic Cavity
Space below the abdomen containing portions of the intestines, rectum, urinary bladder, and reproductive organs
Peritoneum
Double-folded membrane surrounding each lung, Pleural means pertaining to the pleura.
Pleural Cavity
Space between the pleural layers
Spinal Cavity
Space within the spinal column (backbones) containing the spinal cord. Also known as the spinal canal.
Thoracic Cavity
Space in the chest containing the heart, lungs, bronchial tubes, trachea, esophagus, and other organs
Ventral (Anterior)
Pertaining to the front
Hypochondriac
Right and left upper regions beneath the ribs
Epigastric
Middle upper region above the stomach
Lumbar
Right and left middle regions near the waist
Umbilical
Center region near the navel
Inguinal
Right and left lower regions near the groin. Also called the iliac regions
Hypogastric
Middle lower region below the umbilical region
RUQ
