Chapter 6: Muscle/Nerve Tissue And Membranes Flashcards
(36 cards)
What are the contractile proteins?
Myosin and actin
Specialized muscle tissue composted of proteins
Myofilaments
Two types of muscle tissue
Striated muscle and smooth muscle tissue
Primary tissue of muscular system
Skeletal striated muscle tissue
What is skeletal striated muscle tissue attached to?
Bone
What is a skeletal striated muscle cell called?
Muscle fiber
Characteristics of skeletal striated muscle fiber
Multi-nucleated, long, cylindrical
What produces the striated appearance of muscle fibers?
Myofilaments
Is skeletal muscle tissue voluntary or involuntary?
Voluntary - controlled by brain
Type of tissue that forms the heart wall
Cardiac striated muscle tissue
Characteristics of cardiac striated muscle tissue
Single nucleus, branched, striated
Junction of cardiac striated muscle tissue
Intercalated discs
Cardiac muscle tissue is voluntary or involuntary?
Involuntary
What types of structures is smooth muscle tissue found in?
Walls of hollow internal organs (blood vessels, stomach,urinary bladder)
Characteristics of smooth muscle cell
Spindle shaped, single nucleus, non-striated
Is smooth muscle tissue voluntary or involuntary?
Involuntary
What makes nerve tissue unique?
Presence of cells that communicate with other cells via electrochemical signals
Ability of cells to communicate by electrochemical signals is called what?
Conductivity
Functional units that create electrochemical signals
Neurons
Long process that conducts signal to another nerve cell
Axon
Smaller processes that receive signals from other nerve cells
Dentrite
Non-conductive cells that support neurons
Neuroglia
Two major types of membranes
Epithelial and synovial membranes
Three types of epithelial membranes
Cutaneous, mucous, serous membranes
