Three kinds of muscle

Skeletal (striated) muscle-voluntary multinucleated formed by fusion of several cells during embryonic development

Single muscle fiber or cell

Muscle fiber is a cell with many nuclei and several

myofibrils

Smooth Muscle Skeletal Muscle- spindle-shaped multinucleated formed by mononucleate involuntary fusion of several cells during embryonic development

Smooth muscle

Cardiac Muscle -cells are striated and branched with

intercalated disks(desmosomes) tying the cells together

Stomach Low power

Stomach High power

Evolutionary convergence of fusiform shapes

Contact with environment

Internal exchanges surfaces

Interstitial fluid-the liquid between the cells; exchanges

nutrients and wastes with the blood in the capillaries and the

cytoplasm in the cells

Small intestine- maximized surface

area

Minimum distance from air to blood

Negative FeedbackControl of room temperature

Negative Feedback

Control of body temperature

Ingestion Digestion (mechanical and chemical) Absorption

Elimination

Basal Metabolic Rate-an endothermic animal’s Calorie

need under complete rest

Men= body wt. X 11

Women= body wt. X 10

Daily Calorie need

For a sessile student= BMR X 1.6

30 min. exercise /day=BMR X 1.7

60 min. exercise /day=BMR X 1.8

90 min. exercise /day=BMR X 1.9

120 min. exercise /day=BMR X 2.0

Endotherms-surface to volume ratio

Ectotherms have a major advantage on energy usage but cannot always be active in temperate regions
