Body Organization: regions, sections, planes, and cavities

Body Organization: directional terms, regions, sections, planes, and cavities April 5, 2016 Anatomical Position The picture shows a body in anatomical position. The person is upright, with arms down and palms to the front.

Anatomical Position All directional terms reference position with regards to anatomical position even if the body in question is in a different position. Example: The head is superior (above) to the feet, whether you are standing up, laying down, or doing a handstand. Directional Terms

Important terms not shown on the diagram: Deep more internal Superficial toward / at body surface Terms are used to describe relative position.

Example: the ribs are anterior to the Directional Term Practice 1 Using your guided notes, answer the following inferior / distal to the hip bones. 1. The knee is _____________________ lateral 2. The ears are _________________________ to the nose.

3. The elbow is on the _________________side of the arm. posterior / dorsal 4. Your naval is _______________________ to your arms. medial 5. Your thumbs are always _____________ to your fingers.

lateral 6. Your heart is _________________________ to your ribs. deep 7. Your shoulders are ________________ to your elbows._ superior / proximal

Directional Term Practice 2 Name a structure that is medial to your eye lateral to your heart . distal to your wrist proximal to your elbow on the posterior side of the hand on the anterior side of the body superficial to the ribs Regional Terms

The body can be divided into two main regions: Axial part the main axis of our body Head, neck, trunk Appendicular part the appendages arms, legs Regional Terms The body can be divided into two main regions: Axial part the main axis of our body Head, neck, trunk

Appendicular part the appendages arms, legs Your femur is on what part of the body? Your sternum is on what part of the body? Regional Terms The body can be divided into two main regions:

Axial part the main axis of our body Head, neck, trunk Appendicular part the appendages arms, legs Your femur is on what part of the body? appendicular Your sternum is on what

Body Planes and Sections The body may be sectioned (cut) along a flat surface called a plane. The three most common planes are: Sagittal (Median) plane (cuts body into left & right) Frontal (coronal) plane (cuts body into front & back) Transverse plane (cross section) (cuts body into superior &

inferior parts) Body Planes and Sections The body may be sectioned (cut) along a flat surface called a plane. Misconception alert! Planes do not have to be in the middle of the body to go by these names. Body Planes and Sections Which plane could be used to separate

the hemispheres of the brain? sagittal Which plane could be used to separate the top and bottom of the kidney? transverse Which plane could be used to separate t The anterior and posterior parts of the body? frontal Body Cavities

Body Cavities In which cavity are the following organs are found: Name both the major and minor divisions. Dorsal, vertebral Spinal cord Ventral, thoracic Lungs Dorsal, cranial

Brain Ventral, abdominal Liver Ventral, pelvic Bladder Ventral, abdominal Small intestine Practice! Look over your notes on: direction, regional, sectional, and cavity terms with a partner for 5

minutes. Then, we will play a game. Game (Round 1) Get a partner and 8 small pieces of tape, and label 1-8. Place the tape on your partners body to match the words. First one wins! Game (Round 1)

1. 2. 3. 4. 5. 6. 7. 8. Medial to the eye Proximal to the knee

Inferior to the neck On the anterior side of the body Distal to the elbow Posterior side of the hand On the axial body On the appendicular body Game (Round 2) switch Game (Round 2) switch 1.

2. 3. 4. 5. 6. 7. 8. Inferior to the heart Distal to the knee On the posterior side of the neck

On the appendicular body On the axial body Medial to the lungs Superior to the waist On the anterior side of the arm Game (Round 3) Write on paper.. 1. 2.

3. Game (Round 3) Write on paper. Identify the sectional cuts. 1. 2. 3.

Game (Round 3) Write on paper. Identify the sectional cuts. 1. 2. 3. Game (Round 4)

Write on paper. Game (Round 4) Write on paper. Identify the body cavities. Use minor classification (not ventral / dorsal). 1. Where the spinal cord is 2. Where the lungs are 3. Where the stomach is 4. Where the ovaries are 5. Where the kidneys are

6. Where the brain is Game (Round 4) Row Teams Write on paper. Identify the body cavities. Use minor classification (not ventral / dorsal). 1. Where the spinal cord is 2. Where the lungs are 3. Where the stomach is 4. Where the ovaries are 5. Where the kidneys are

6. Where the brain is Homework Test next class
