What is it? Anatomy: the branch of science that deals with the structure of body parts Physiology: concerns the functions of body parts, what they do and how they do it
Levels of Organization Atoms: microscopic particles Molecules: made up of atoms Macromolecules: molecules combined in complex ways Cell: Basic unit of living thing Organelle: structures within a cell that perform a certain task Tissue: Group of cells Organs: Complex structures made up of tissues that perform a certain task Organ system: Group of organs working together Organism: Organs make up living things
Characteristics of Life Metabolism: process of chemical reactions in the body that break down substances and build them up for energy Maintenance of Life Water, Foods, Oxygen, Heat, Pressure Homeostasis: Maintaining a stable internal environment for survival (Temp, pH, water, etc.)
Homeostatic Mechanisms Receptors: provide information about specific conditions in the internal environment Set Point: tells what a particular value should be (body temp) Effectors: cause responses that alter conditions in the internal environment
Homeostatic Mechanisms Set Point Change is compared to the set point Receptors Effectors Stimulus Response (Change is corrected)
Body Portions Axial Portion: Includes head, neck, and trunk Appendicular Portion: Includes upper and lower limbs
Anatomical Positions Superior: Body part is above another part, or closer to the head Inferior: body part is lower than another, toward the feet Anterior: Towards the front (Eyes are anterior to the brain) Posterior: Towards the back Medial: Imaginary midline dividing the body into equal right and left halves.
Anatomical Positions Lateral: toward the side with respect to the midline (Ears are lateral to the eyes) Bilateral: refers to paired structures, one on each side (lungs) Ipsilateral: structures on the same side (right kidney and right lung) Proximal: Body part that is closer to the trunk (elbows are proximal to wrist) Distal: Opposite of proximal, farther away from trunk Superficial: placed near the surface of the skin Deep: more internal parts
LEFT SIDE ACTIVITY Choose 10 vocabulary words from the slides and define the words and draw a picture or use the word in a sentence. Draw and label your own anatomical person. Use all 14 of the vocab words we just went over and give examples as necessary.
