A + P Lesson 1 Flashcards
Define Anatomy
The study of the STRUCTURE AND SHAPE of the body and it’s parts, and their relationships to one another
Define Physiology
study of how the body and it’s parts work or FUNCTIONS
The relationship between anatomy and physiology
Structure determines Function
Name the six directional terms:
- superior/cranial/cephalad
- inferior/caudal
- ventral/anterior
- dorsal/posterior
- medial
- lateral
superior/cranial/cephalad definition:
above, towards the head
inferior/caudal definition:
down, towards the tail
ventral/anterior definition:
in the front, or stomach
dorsal/posterior definition:
towards the back
medial definition:
the midline of the body, anything going in towards the middle.
lateral definition:
anything going away from the median of the body
intermediate definition:
in between
proximal definition:
in towards the body
distal definition :
out towards your extremities
superficial definition:
skin
deep definition:
deeper organs
the wrist is proximal to the _________
fingers
the wrist is distal to the ___________
elbow
superficial usage
the skin is superficial in relation to the organs
deep usage
the organs are deep in relation to the skin
the three planes are:
- sagittal
- frontal/ coronal
- transverse
sagittal section/plane definition:
a cut along the lengthwise, or longitudinal, plane of the body, dividing the body into right and left parts. If the cut is down the median plane of the body and the right and left parts are equal in size, it is called a MEDIAN, or MIDSAGITTAL, SECTION. All other sagittal sections are parasagittal sections.
Frontal/ coronal section/plane definition:
a cut along a lengthwise plane that divides the body (or and organ) into anterior and posterior parts.
Transverse section/plane definition:
a cut along a horizontal plane, dividing the body or organ into superior and inferior parts.
name the 3 body cavities :
2 main body cavities:
- Dorsal
- Ventral
- abdominopelvic
- dorsal
- ventral
Dorsal Cavity definition:
- cranial
- spinal
Ventral cavity definition:
- thoracic
- abdominal
- pelvic
abdominopelvic cavity definition:
- hypochondriac
- epigastric
- lumbar
- umbilical
- Iliac
- Hypogastric/Pubic
How the body works…..
homeostasis, functions, organization, and organ systems
Essential Human needs :
water, nutrients, oxygen, appropriate temperature, appropriate pressure
Essential human functions:
Maintain boundaries, movement, responsiveness, digestion, metabolism, excretion, reproduction, growth
