Near ANATOMY 3023 By Brian Matchett and Alyson Walaskay

Slide 2

WHAT IS COMPARATIVE ANATOMY?

Slide 4

Comparative Anatomy The investigation of and correlation of body parts of various species

Slide 5

Comparative Anatomy Includes: Change, adjustment, and transformation of species The intrusion of new domains Species similarity with environment

Slide 6

How Can Comparative Anatomy Help Us? Comprehend our history Consider gets ready for change Improve creature hereditary qualities Preserve imperiled species

Slide 7

Why Should We know about Comparative Anatomy? Varieties in tend to creatures Differences in creature propensities

Slide 8

Adaptation Genetic and physiological changes that happen because of weights or changes in a creature\'s domain

Slide 9

Adaptation Changes Examples: Forelimb of people utilized for controlling Webbed foot of seal utilized for swimming Front feet of a mole utilized for burrowing

Slide 10

Structural Development Homologous Structures Analogous Structures

Slide 11

Homologous Structures Have comparable structures, yet distinctive utilizations E.g. Turtle leg and flying creature wing

Slide 12

Analogous Structures Body parts comparative being used, however diverse in structure E.g. Flying creature wing and creepy crawly wing

Slide 13

Directional Terms Used to portray the positions of structures on the body in respect to different structures or areas

Slide 14

Cranial – nearer to the leader of the creature Caudal – nearer to the tail Medial – nearer to the midline of the appendage, trunk or head Lateral – more distant far from the midline

Slide 16

Dorsal – close decay the top side (back) of the creature Ventral – nearer to the base side (paunch) of the creature Proximal – nearer to the connection of the extremity to the body Distal – more distant far from the connection of the body

Slide 17

Comparative Anatomy of Typical Farm Animal Species Includes Skeletal Structures Reproduction Digestive Systems

Slide 19

Skeletal Structures Protects imperative organs and gives fundamental frame and shape to a creatures body

Slide 20

Reproduction The generation of live, ordinary posterity

Slide 22

Puberty – age at which regenerative organs turn out to be functionally agent Gestation – time from rearing or origination of a female until she brings forth her young Estrus – time for acknowledgment of the male and ordinarily coincides around with ovulation "Heat" Estrous Cycle – Estrus cycle or the time from one estrus to the next

Slide 23

Digestion Includes every one of the organs that are included in the absorption of nourishment

Slide 25

Types of Digestion Monogastric or Simple Stomach Ruminant Avian

Slide 26

Monogastric Characterized by the failure to process roughage productively Enzymes used to separate sustenance Includes: people, swine, rabbits and stallions

Slide 28

Ruminant Handles the breakdown of extensive sums lignified fiber Has four unique compartments: Rumen - Omasum Reticulum - Abomasum Includes: sheep, bovines, goats

Slide 30

Avian Designed for granulating hard or encased sustenance Has a gizzard Have no teeth Includes: all flying creatures
