The Human Body: Anatomical Regions and Directions

Bell Work 3 -14 -18 1. Name three types of muscles? 2. What type of muscle attaches to bone and allows for movement? 3. What are the involuntary muscles? 4. What muscle straightens the ankle joint so you can stand on tiptoes? 5. What muscle holds and rotates your shoulders and moves your head back and sideways?

Standard 10) Investigate the basic principles of kinesiology and relate in an informational paper, brochure, or presentation the connection to disease/disorder prevention. Address at minimum: movements of joints and bones, planes, directional terms, body motions, motions between joint articular surfaces, mechanisms of joints and biomechanical levers. 3

Objectives • At the conclusion of this lesson I CAN: – Model the anatomical position – Differentiate between various directional terms and model their position – Identify the body planes – https: //www. youtube. com/watch? v=kv. HWn. Jw Bkmo

Why do we need to learn body directions?

Body Planes • Sagittal – divides the body into right and left parts • Frontal or coronal – divides the body into anterior and posterior parts • Transverse or horizontal (cross section) – divides the body into superior and inferior parts

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 Figure 1. 8

Body Planes and Sections Which plane could be used to separate the hemispheres of the brain? Which plane could be used to separate the top and bottom of the kidney? Which plane could be used to separate the anterior and posterior parts of the body?
