Introduction Flashcards
Define Anatomy
Study of Structure
Define Gross Anatomy
Study of macroscopic structure
Define Physiology
Study of function
List the 6 levels of structural organization and an example of each
Molecular-Glucose
Cell-muscle cell
Tissue-connective tissue
Organ-Stomach
Organ system- digestive system
Organism-Human being
Describe anatomical position
Standing erect Arms down by your side Palms facing forward
Medial/Lateral
Towards and away from midline
Proximal/distal
Towards trunk and away from trunk
Anterior/posterior
Front/back
Superior/inferior
Above/below
External/internal
Outer/inner
Superficial/deep
External/internal
Ventral/dorsal
Front/back
Cranial/caudal
Towards head/away from head
Ispsilateral/contralateral
Same side of body/opposite side of body
Define the Transverse plane
Divides you into superior and inferior portions
Define the sagittal plane
Divides you into left and right portions
Define the frontal plane
Divides you into anterior and posterior portions
What are the major body cavities
- Dorsal 2. Ventral 3. Thoracic 4. Abdominal 5. Pelvic
Dorsal Cavity
Containing the cranial cavity and spinal cord
Ventral
Divides into thoracic and abdominal
Thoracic
Heart and lungs
Abdominal
Liver, stomach, intestines
Pelvic
Rectum, reproductive organs
What is homeostasis
Balance or steady state. If your body temp is too low, you shiver. Once it reaches a normal temp., you STOP the process of shivering.
Negative feedback
Undoes the deviation from normal
Positive feedback
Positive feedback does not lend itself towards homeostasis & would be the process of a small blood clot leading to a bigger one and an even bigger one etc…
