Basic Elements of Anatomy Flashcards
Descriptive Anatomy
Individual parts of the body
(homogenous)
Gross Anatomy
Anatomy of Visible Structures
Pathological Anatomy
Structural changes related to disease or disorder
Developmental Anatomy
Structural changes as related to development
Neurology
Study of the nervous system
Supine
lying down, face up
Prone
Lying down, face down
Anterior
Toward the front
Posterior
Toward the back
Superior
Upper, toward the head
Inferior
Lower, toward the feet
Medial
Toward the midline
Lateral
Away from the midline
Superficial (external)
toward the surface

Posterior
Upper, toward the head
Superior
Lower, toward the feet
Inferior
Toward the midline
Medial
Away from the midline
Lateral
Deep or internal
away from the surface
Proximal or central
toward the body or center
Distal or peripheral
away from the body or center
Sagittal
vertical plane that divides the body into right and left portions
Midsagittal
Special when cut at midline
left and right halves
Frontal (Coronal)
Intersects the sagittal
Parallel to forehead
Transverse
Divides the body into upper and lower parts
Types of Tissues (4)
Epithelial
Connective
Muscular
Nervous
Ciliated Epithelium
(simple columnar ciliated)
Line the nasal cavity, larynx, trachea, and bronchii
Squamous Epithelium
(Simple flat)
line the alveoli in the lungs where oxygen transfer takes place
Stratified Epithelium
(compound squamous on top of columnar)
line oral cavity, pharynx, and esophagus -Food pathway
Epithelial
Formed by closely approximated cells with little intercellular substance
Connective Tissue
Connect or bind structures together. Combination of cells and extra-cellular substance
Types of Connective Tissue
Loose Connective Tissue
Dense Connective Tissue
Bone
Loose Connective Tissue (Areolar)
Found beneath the skin
- Collagen membrane under epithelium
- Adipose areolar tissue = high fat cells
- Fascia surrounds organs and muscles
Tendons
Bone to Cartilage
Fibers course in same direction as muscle
Ligaments
Bone to bone, bone to cartilage, cartilage to cartilage
Fibers course in a uniform direction
Cartilage
Cushions bones and provides body structure
- Costal Cartilages: rib cage, larynx, trachea
- Nose, pinna, epiglottis
- Vertebrae
Bone
- Composed of cells, collagenous fibers, and inorganic salts
- Lots of intercellular substance (calcium)
- Lamellar structure (thin alternating layers of collagenous fibers and matrix)
- Covered by periosteum

Areolar Tissue
What Type of Tissue?
Where is it found?
Main type of Loose Connective Tissue
Found just beneath the skin
Adipose Areolar Tissue
Type of areolar tissue that has high concentration of fat
Types of Epithelial Tissue (3)
- Ciliated Epithelium
- Squamous Epithleium
- Stratified Epithelium
Ciliated Epithelium Tissue
simple columnar epithelium
line nasal, larynx, trachea, & bronchii
Squamous Epithelium Tissue
Simple Flat
Line the alveoli in lungs
Stratified Epithelium
Compound Squamous on top of columnar
oral cavity, pharynx, & esophagus
food pathway
Muscle Tissue Types (3)
Striated
Smooth
Cardiac
Striated Muscle
involuntary or voluntary?
AKA..?
How are they arranged?
Voluntary Control
AKA Skeletal Muscle
Arranged in parallel bundles
Smooth Muscle
Involuntary? Voluntary?
How are they organized?
Involuntary
Less organized
Point of attachment for least mobile element
Origin
Point of maximum movement for muscles =
Insertion
Muscles that are Prime Movers are called
Agonist
Muscles which oppose contracting muscles are
antagonist muscles
Muscles that stabilize structures
Synerist Muscles
In nervous tissue-
Dendrites send or receive signals?
Axons send or receive signals?
Dendrites receive
Axon send
