Unit 3
Objectives
MAIN OBJECTIVES
The main objectives for Anatomy and Physiology are:
- To compare and contrast the various systems of the body.
- To identify the structures on models and specimens.
- To be able to discuss the functions of the systems and structures.
- To discuss the internal and external impacts on the human body.
- To show the interrelationship between structure and function of the entire organism.
Specific objectives for unit three:
- Muscle Tissue
- List the characteristics and functions of muscle tissue.
- Compare the location, microscopic appearance, nervous control, functions, and regenerative capabilities of three kinds of muscle tissue.
- Describe the importance of a neuromuscular junction and a motor unit.
- Describe the principal events associated with the sliding filament mechanism of muscle contraction.
- Identify the sources of energy for muscular contraction.
- Explain how muscles affect homeostasis of body temperature.
- Explain how muscle tension can be varied.
- Describe the different types of skeletal muscle fibers and compare them to cardiac and smooth muscle fibers.
- Define some of the common muscular disorders.
- The Muscular System
- Describe the relationship between bones and skeletal muscles in producing body movements.
- Define a lever and fulcrum and describe the three classes of levers with respect to fulcrum, effort, and load. Identify the various arrangements of muscle fibers in a skeletal muscle and relate the arrangements to strength, contraction, and range of motion.
- Discuss muscles in terms of prime mover, antagonist, synergist, and fixator.
- Define the criteria in naming skeletal muscles. Identify the principal skeletal muscles of the body by name, origin, insertion, action, and innervations.
- Nervous Tissue
- Identify the three basic functions of the nervous system in maintaining homeostasis.
- Classify the organs of the nervous system into central and peripheral divisions.
- Contrast the characteristics and functions of neuroglia and neurons.
- Describe the functions of neuroglia.
- Describe the structure and functions of neurons.
- Define white and gray matter and give examples of each.
- Describe the cellular properties that permit communication among neurons and muscle fibers.
- Explain the events of synaptic transmission.
