Chapter 10 (Muscular Tissue II) Flashcards
Functions of Muscular Tissue
Producing Body Movements
Stabilizing Body Positions
Moving Substances Within the Body
Generating heat
Functions of Muscular Tissue (Examples)
Walking and running Posture Heart muscle pumping blood Moving substances in the digestive tract Controlling movements using sphincters Contracting muscle produces heat Shivering increases heat production
Properties of Muscular Tissue
Excitability, Contractility, Extensibility, Elasticity
Excitability (Properties of Muscular Tissue)
Ability to respond to stimuli
Contractility (Properties of Muscular Tissue)
Ability to contract forcefully when stimulated
Extensibility (Properties of Muscular Tissue)
Ability to stretch without being damaged
Elasticity (Properties of Muscular Tissue)
Ability to return to an original length
Connective Tissue Components
Fascia, Epimysium, Perimysium, Endomysium, Tendon, Aponeurosis
Fascia (Connective Tissue Components)
Dense sheet of irregular connective tissue that surrounds groups of muscles with similar function, forming compartments
Epimysium (Connective Tissue Components)
The outermost layer of a single muscle
Perimysium (Connective Tissue Components)
Separates 10-100 muscle fibers into bundles called fascicles
Endomysium (Connective Tissue Components)
Separates individual muscle fibers from one another
Tendon (Connective Tissue Components)
Cord that attaches a muscle to a bone
Aponeurosis (Connective Tissue Components)
Broad, flattened tendon
