Body Planes Directions and Cavities Health Science I

Body Planes, Directions, and Cavities Health Science I Mrs. Berry

Objectives • Label a diagram of the three planes of the body with the names of the planes and the directional terms created by these planes • Label a diagram of the main body cavities

Objectives Cont…. • Identify the main organs located in each body cavity • Locate the four quadrants and the nine abdominal regions • Define, pronounce, and spell all of the key terms

Take notes in your health science notebook • After each new lesson, you will be required to complete an activity. • Each activity will be graded for classwork at the end of the week. • All activities will stay in your spiral notebook. By doing this you will have all your notes together. This makes studying for a quiz, text, midterm and exam much easier.

Body Planes: • Definition = imaginary lines drawn through the body to separate the body into sections

Transverse Plane: Horizontal plane dividing the body into a top and bottom half 1. Superior = body parts above other parts 2. Inferior = body parts below other parts

Sagittal Plane Divides the body into right and left sides 1. Medial = body parts located near the middle or midline of the body 2. Lateral = body parts located away from the midline or middle of the body

Frontal Plane: Divides the body into front and back section. 1. Anterior = body parts on the front of the body 2. Posterior = body parts on the back of the body

Label your paper body planes write the correct term next to each letter

Body Plane 3. Cranial = body parts near the head 4. Caudal = body parts located near the sacral region of the spinal column (or near the tail bone)

Body Cavities: Spaces within the body which contain vital organs

Dorsal Cavity One long continuous cavity that is located on the back of the body, divided into two sections 1. Cranial Cavity = contains the brain 2. Spinal Cavity = contains the spinal cord

Ventral Cavities: Larger and separated into two distinct cavities by a dome-shaped muscle called the diaphragm, which is important for breathing 1. Thoracic Cavity = located in the chest, contains the heart, lungs, and the large blood vessels

Ventral 2. Abdominal Cavity = divided into upper and lower parts Upper part contains the stomach, small intestines, most of the large intestines, liver, gallbladder, pancreas and spleen 3. Pelvic Cavity = lower abdominal cavity containing urinary bladder, the reproductive organs, and last part of the large intestines

Label your paper body cavities 1 -7 write the correct term

Abdominal Regions: Quadrants 1. 2. 3. 4. Right Upper Quadrant (RUQ) Left Upper Quadrant (LUQ) Right Lower Quadrant (RLQ) Left Lower Quadrant (LLQ)

Label your paper abdominal Quadrants, draw four boxes and the correct term in each box.

Abdominal Regions: • • • Epigastric Umbilical Pelvic Hypochondriac Lateral Inguinal

Label your paper abdominal regions write the correct term for each letter a-i

Directions • Proximal = body parts close to the point of reference • Distal = body parts away from the point of reference

Number your paper 1 -12 Write the correct term next to the definition
