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

Slide 67 Nerve Fibers
Myelin sheath produced by
Schwann cells
Processes
Cell body
Nucleus
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
Crab lab-calorimeter
Maximum metabolic rates over
different time spans
Total annual energy expenditures
Endotherms-surface to volume ratio
Ectotherms have a major advantage on energy usage but cannot always be active in temperate regions
