structural organization
Structural Organization
  • Cells
    • Smallest, most numerous structural unit
  • Tissues
    • Groups of similar cells with specialized functions
structural organization1
Structural Organization
  • Organs
    • Tissues arranged together to perform a particular function
  • Body systems
    • Organization of different organs to perform bodily functions
terms relating to cells

  • Aplasia
  • Dysplasia
  • Hyperplasia
  • Hypoplasia
  • Neoplasia
types of tissues
Types of Tissues
  • Connective
  • Epithelial
  • Muscle
    • Skeletal
    • Smooth or Visceral
    • Cardiac
  • Nervous
question
Question

The _______ are the smallest structural units, leading up to ______________, which perform important bodily functions.

  • tissues, organs
  • body systems, cells
  • cells, body systems
  • cells, organs
question1
Question

Of the 4 types of tissue, how many do you think are involved in a body system such as the digestive system?

  • 4
  • 3
  • 2
  • None
body planes
Body Planes
  • Midsagittal
    • Divides body into equal right and left portions
    • Midline of the body
    • Medial
    • Lateral
body planes2
Body Planes
  • Frontal or coronal
    • Divides body into front and back portions
body planes4
Body Planes
  • Transverse
    • Cuts across body
    • Superior (cranial, cephalic)
    • Inferior (caudal)
question2
Question

True or False: A frontal view is when you divide the body into equal left and right portions.

question3
Question

True or False: A radiologist dictates a craniocaudal view was performed. This means the film was shot from the top of the head downward toward the tail.

body regions
Body Regions
  • Nine abdominal regions
    • Identified from left to right
    • Move from top to bottom
    • One row at a time
abdominal quadrants
Abdominal Quadrants
  • Landmark = umbilicus (navel)
  • Quadrants
    • RUQ, LUQ, RLQ, LLQ
    • McBurney’s point
    • Munro’s point
question4
Question

Looking at the diagram of the 9 body regions, what number would be the right lumbar region?

  • 3
  • 6
  • 8
  • 7
question5
Question

True or False: McBurney’s point is the landmark for the 4 abdominal quadrants.

body cavities
Body Cavities
  • Ventral cavity
    • Thoracic
    • Abdominal
    • Pelvic
  • Dorsal cavity
    • Cranial
    • Spinal
question6
Question

True or False: Basically, anything in front of the spine is considered a ventral cavity.

question7
Question

The ___________ cavity is separated by the diaphragm from the ___________ cavity.

  • pelvic, abdominal
  • abdominal, thoracic
  • thoracic, pelvic
  • thoracic, abdominopelvic
divisions of the back
Divisions of the Back
  • Cervical vertebrae (C1 – C7)
  • Thoracic vertebrae (T1 – T12)
  • Lumbar vertebrae (L1 – L5)
  • Sacrum
  • Coccyx
question8
Question

When describing a vertebral body’s location, you will use the _________ letter of each division.

  • second
  • last
  • first
  • next to last
question9
Question

True or False: As long as you know where the divisions are in the spine, you can count from either the top or the bottom to correctly identify each vertebra.

directional terms
Directional Terms
  • Superficial vs. Deep

  • Cranial vs. Caudal
directional terms2
Directional Terms
  • Medial vs. Lateral
  • Distal vs. Proximal
  • Supine vs. Prone
  • Supination vs. Pronation
  • Plantar vs. Dorsal
question10
Question

Common nouns can help in keeping directional terms straight. For instance, something in close proximity is __________ and something that is in the distance is __________.

  • medial, lateral
  • distal, proximal
  • superior, inferior
  • proximal, distal
