INTRO LECTURE Flashcards
Anatomical maps are called ______
Atlases
definition of the anatomical position
standing squarely on all four limbs with head and tail extended
what does it mean that vertebrates are bilaterally symmetrical?
they have mirrored right and left sides
towards the back
dorsal
towards the belly
ventral
closer to the head
rostral (also can use cranial)
closer to the tail
caudal
the _____ plane is one, unique, longitudinal plane dividing the animal into (imaginary) perfect right and left halves
MEDIAN plane
on the same side
ipsilateral
on opposite side
contralateral
towards the midline
medial
away from the midline
lateral
longitudinal planes
parallel to the median plane
dorsal plane divides the body into ‘top’ or ‘bottom’
transverse plane divides the body into cranial and caudal
In LIMBS, the _______ region is closer to the trunk (origin)
proximal
in LIMBS, the _______ region is further away from the origin (tunk)
distal
Light Microscopy (LM)
Photons interact with tissue components, light is focused w/ optical lens
Electron Microscopy (EM)
electrons interact w/ tissue components (tissue has been manipulated)
Transmission Electron Microscopy (TEM)
shows INTERNAL structure
Scanning Electron Microscopy (SEM)
shows EXTERNAL (surface) structure
2 basic types of stains
basophilic (acid stain)
acidophilic (base stain)
Basophilic stains
interact with acidic (basophilic) structures
- acidic components appear blue or purple
Acidophilic stains
interact with basic (acidophilic) structures
- basic components appear pink,red,orange
most common stain type
H&E (hematoxylin and Eosin)
hematoxylin = basophilic stain
eosin = acidophilic stain
