Muscle Tissue And Nervous Tissue Flashcards
What are the fibers in muscle tissue?
Muscle fibers
What are the 3 types of muscle tissue?
Skeletal muscle, smooth muscle, and cardiac muscle
Characteristics of skeletal muscle:
Long, cylindrical cells; striations; attach to bones throughout the body
What is the function of skeletal muscle?
Voluntary movement, manipulation, facial expression
Skeletal muscle: voluntary or involuntary
Voluntary
Characteristics of cardiac muscle:
Branching, striated cells; intercalated discs
Where is cardiac muscle found?
Walls of heart
What is the function of cardiac muscle?
Propels blood into circulation
Cardiac muscle: voluntary or involuntary?
Involuntary control
Characteristics of smooth muscle:
Spindle-shaped cells; NO STRIATIONS; form sheets
Where is smooth muscle found?
Walls of hollow organs
What is the function of smooth muscle?
Propels substances along passage ways (food, urine, fetus)
What is the primary cell type in nervous tissue?
Neurons
What is the function of nervous tissue?
Transmits electrical signals from sensory receptors to effectors; support and protects neurons
Where is nervous tissue found?
