  1. The Human Body: Directional Terms

  2. Muscular System Bell Ringer: (page 71) Instructions: Turn to page 71 and answer the question below. How is finding the different muscles in the human body like going on a road trip? List two ways.

  3. Muscular System Finding Your Way: • Need a correct and current map • Need to know where you are (a point of reference or starting point) and where you are going. • Need to use terms with others that are mutually understood (a common language)

  4. Muscular System Finding the different muscles in your body, works the same way: • Need correct and current map (in your packet) • Need to know where you are (a point of reference or starting point) and where you are going • Need a common language (terms) We need these terms to help us understand what we are looking at and to help us find the muscles we are looking for.

  5. Muscular System Preview Vocabulary: Anatomical Position Anterior / Posterior Midline Lateral / Medial Superior / Inferior Proximal / Distal

  6. Muscular System LEQ: What are the responsibilities of the different muscle groups in our bodies?

  7. Muscular System Anatomical Position: point of reference • Body upright • Feet slightly apart • Palms facing forward • Thumbs point away from body All directional terms we will discuss today refer to the body in anatomical position (this is everyone’s starting or reference point). What are the responsibilities of the different muscle groups in our bodies?

  8. Muscular System Directional Terms: Anterior– the front of the body or toward the front of the body. Posterior– the back of the body or toward the back of the body What are the responsibilities of the different muscle groups in our bodies?

  9. Muscular System Directional Terms: Anterior / Posterior • Examples: • Anterior • the sternum is on the anterior side of the body • the biceps muscle is anterior to the ____________ • Posterior • the spinal column is on the posterior side of the body • the hamstrings are posterior to the _____________ What are the responsibilities of the different muscle groups in our bodies?

  10. Muscular System Directional Terms: Midline– an imaginary line running from the forehead to the ground (cuts the body into left and right halves) Examples: Trachea, Esophagus, Nose, Belly Button What are the responsibilities of the different muscle groups in our bodies?

  11. Muscular System Directional Terms: Medial-- toward the midline Lateral-- away from the midline What are the responsibilities of the different muscle groups in our bodies?

  12. Muscular System Directional Terms: Examples: Medial • the heart is medial when compared to the lungs • the pectoralis major is medial when compared to the mid-deltoid Lateral • the lungs are lateral when compared to the heart • the external obliques are lateral to the _______________ What are the responsibilities of the different muscle groups in our bodies?

  13. Muscular System Directional Terms: Superior– towards the head or upper part of a structure; above Inferior– away from the head or lower part of a structure; below Superior Inferior What are the responsibilities of the different muscle groups in our bodies?

  14. Muscular System Directional Terms: Examples: Superior • the lungs are superior to the liver • the pectoralis major is superior to the rectus abdominis Inferior • the small intestines are inferior to the stomach • the gastrocnemius is inferior to the _____________ What are the responsibilities of the different muscle groups in our bodies?

  15. Muscular System Directional Terms: Proximal– closer to the point of attachment of a limb to the body Distal – farther from the point of attachment of a limb to the body What are the responsibilities of the different muscle groups in our bodies?

  16. Muscular System Directional Terms: Examples: Proximal • the elbow is proximal when compared to the wrist Distal • the ankle is distal when compared to the ______________ What are the responsibilities of the different muscle groups in our bodies?

  17. Muscular System Summarizer: Numbered heads Show your partner and explain or provide an example of the following terms: • the anatomical position • anterior/posterior • the midline • medial/lateral • superior/inferior • proximal/distal What are the responsibilities of the different muscle groups in our bodies?
