Intro to Functional Anatomy

study set created from the 1st ppt, Introduction to functional Anatomy

Positive Reinforcement (pos + neg)

adding something the animal wants in order to increase the likelihood that the behavior will occur again

punishment (pos + neg)

anything that decreases the likelihood a behavior will occur again

is a rabbit a rodent?

no, rodents include mice, rats, and guinea pigs—> etc

Lagomorphs

ex: hares, rabbits, pikas

-two pairs of incisors in the maxilla (peg teeth), maxillary fenestrations

-incisors surrounded by a single, unpigmented layer of enamel

-strictly herbivorous

-short tails

Rodents

ex: mice, rats, guinea pigs

-single pair of incisors

-double-layered unpigmented layer of enamel

-not strictly herbivorous

-long tails

-penis bone (“baculum”)

dog domestication

domesticated twice (Asia & Europe)

a deep divide between each dog type - (Asia: Shar Pei) + (Europe: golden retriever)

cat domestication

the wildcat (F. S. lybica) was a common ancestor to house cats

-domesticated in Africa & Middle East

-China: the leopard cat (prionailurus bengalensis) adapted independently.

-1960s: leopard cats x domestic cat —> Bengal breed

Bengal Cat appearance description

rosetted spots occur only on the back and sides, with stripes elsewhere

functional anatomy

the study of anatomy in its relation to function; concurrent presentation of anatomy with physiology

comparative anatomy

the study of the body structures of different species of animal

comparative physiology

the science concerned with the differences in the vital processes in different species of organisms

structure is always related to function; if structure changes, function change
