Chapter 1 - Intro Flashcards
Two branches of science that deal with body’s parts and function
Anatomy & Physiology
Anatomy
The science of body structures and relationships
- First studies by dissection (cutting apart)
- Imaging techniques
Physiology
The science of **body functions **
Basic Life Processes (6)
1) metabolism
2) responsiveness
3) movement
4) growth
5) differentiation
6) reproduction
Descriptions of the human body assume a specific stance - **Anatomical position **(6)
body upright
standing erect facing observer
head & eyes facing forward
feet are flat on the floor & forward
upper limbs to sides
palms turned forward
Terms for a reclining body (2)
1) prone
2) supine
**Prone **position
body is lying face down
**Supine **position
body is lying face up
**Directional Terms **
describe the?
position of one body part **relative to another **
group in pairs with opposite meaning
Directional Terms for front & back
**anterior **(front) view
**posterior **(back) view
___________ Nearer to the front of the body
anterior
___________Nearer to the back of the body
posterior
___________Toward the head
superior
___________Away from the head
inferior
___________Nearer to the attachment of a limb to the trunk
proximal
___________Farther from the attachment of a limb to the trunk
distal
___________Farther from the midline
lateral
___________Nearer to the midline
medial
____ between 2 structures
intermediate
__________ same side as another structure
ipsilateral
__________ opposite side as another structure
contralateral
__________ toward or on surface of body
superficial (external)
________away from surface of body
deep (internal)
Most Principal Regions (5)
Head
Neck
Trunk
Upper Limbs
Lower Limbs
Head Region
skull & face
Neck Region
Supports the head and attaches to trunk
Trunk Region
chest, abdomen, pelvis
Upper Limb Region
attaches to trunk (shoulder, armpit & arm)
Lower Limb Region
attaches to trunk (buttock, thigh, leg, ankle & foot)
Planes
imaginary flat surfaces that pass through the body parts
Sagittal plane
a vertical plane that divides the body into right & left sides
Midsagittal plane
divides body into equal right and left sides
Parasagittal plane
divides body into unequal right and left sides
**Frontal **or **Coronal **plane
Divides the body or an organ into anterior (front) and posterior (back) portions
**Transverse **plane
Divides the body or an organ into superior (upper) and inferior (lower) portions
Also called cross-sectional or horizontal plane
