Chapter 1 a&p 1

  1. What is Anatomy?
    Study of the structure and shape of the body and their body parts and how they relate to each other.
  2. What is Physiology?
    The study of how the body and its parts work or function
  3. What is homeostasis?
    Is your body’s ability to maintain healthiness even though there is continuous change in the outside world. When the body’s needs are being met, the body is in a homeostatic state
  4. FCL
    Communication in the body is essential for homeostasis to occur. The communication networking is called a “feedback control loop.” When the body self regulate
  5. 4 Components of FCL
    • Sensor Mechanism (brain saying pain)
    • Control or Integrator Center (Body felling the pain)
    • Effectors' mechanism (your response to the pain)
    • Feedback( your body saying if the effectors worked or not)
  6. What Does the Body Do?
    • 1) Maintaining Boundaries
    • the out side germs stay away from the inside of your body
    • 2) Movement
    • muscular system promotes movement
    • 3) Responsiveness (irritability)
    • Is the 1 and 3 component in FCL
    • 4) Digestion
    • breaking down of food for absorption
    • 5) Metabolism
    • all chemical reactions within the body
    • 6) Excretion
    • is the removing waste
    • 7) Reproduction
    • responsible for producing offspring
    • 8) Growth
    • increase in the size of a body part
    • ● Chemical Level
    • Building blocks of nature – it has atoms
    • molecules
    • ● Cellular Level
    • Cells –is the most numerous structural units of living matter.
    • ● Tissue Level
    • Is a group of many similar cells that all developed together from the same part of the embryo and all perform a certain function.
    • ● Organ Level
    • The structure is made up of several different kinds of tissues to perform a special function.
    • For example – Heart
    • Other Examples…….
    • ● System Level
    • Is the most complex organization of the organizational units
    • it Involves different organs coming together to perform a complex function.
    • ●Organism Level
    • “The Human Body”
  8. Survival Needs
    • Nutrients
    • Oxygen
    • Water
    • “Normal” Body Temperature
    • Appropriate Atmospheric Pressure (the force that air exerts on the surface of the body)
    • The “amounts” are important to ensure quality of life.
    • (When the body’s needs are being met, the body is in a homeostatic state)
    • Body is erect.
    • Arms at side.
    • Palms forward.
    • Head and feet forward.
  10. Body planes
    • Ipsilateral – on the same side
    • Contralateral – opposite sides
    • Bilateral Symmetry- The left is the same as the right
    • Ventral Cavity – Includes the thoracic (chest) cavity and the abdomino pelvic cavity.
    • Dorsal Cavity – Includes the cranial cavity and spinal cavity
    • Sagittal Plane -Divides the body into left and a right
    • Transverse Plane (Cross) - Divides the body into superior and inferior
    • Frontal Plane (Coronal)Divides the body into anterior and posteriorImage Upload 1
