| Question | Answer |
|---|---|
| The ability of the skeletal muscles to shorten with force. | Contractility |
| Each muscle is surrounded by a connective tissue sheath called_________ | Epimysium |
| Myofibrils consist of 2 major kinds of protien fibers: ________ & ________ | Actin Myofilaments & Myosin Myofilaments |
| These muscles raise the eyebrows | Occipiofrontalis |
| Nerve cells that carry action potentials to skeletal muscle fibers | Motor Neurons |
| The acetylcholine released into the synaptic cleft between the neuron and the muscle cell is rapidly broken down by an enzyme | Acetylcholinesterase |
| Neede for energy for muscle contraction | ATP |
| Is a contraction of an entire muscle | Muscle Twitch |
| Muscle cells | Muscle fibers |
| Results when ATP is used during muscle contraction faster then it can be produced in the muscles. | Muscle Fatigue |
| The constant tension produced by muscles of the body for a long period of time. | Muscle Tone |
| The most stationary end of the muscle | Origin |
| Move the vertebral column | Trunk Muscle |
| Flexes the vertebral column | Rectus abdominis |
| Muscles that work together to accomplish specific movements | Synergists |
| The basic structural and function unity of the muscle made up of actin and myosin myofliamnets | Sacromere |
| The length of the muscle does not change, but the amount of tension increases during the contraction. | Isometric |
| Characteristics of the skeletal muscles | Excitability, elasticity, contractility, and extensibility |
| Connective tissue that seperates muscles and surrounds the epimysium is called_____ | Fascia |
| Extends from a Z line to the next, has a H-zone in the center, and contains overlapping actin and myosin | Sacromere |
| The condition in which a muscle remains contracted without relaxing is called_____ | Tetany |
| A high energy molecule that can be quickly used to produce ATP | creatin phosaphate |
| If someone winks at you, they are using the_______ | Orbicularis Oculi |
| Muscle responsible for elevating the ribs during respiration | External Intercostals |
| Hip Muscle | Gluteus maximus |
| An anterior thigh muscles that extends the leg | Quadriceps Femoris |
| Muscle fiber is surrounded by | Endomysin |
| 2 layers that surround the muscle | epimysin and perimysin |
| A contraction of an entire muscle in response to stimulus | muscle twitch |
| Occurs in the presence of oxygen | Areobic respiration |
| 2 muscle disorders | cramps and hypertrophy |
| muscle fibers fatigue quickly | Fast twitch |
| The most stationary end of the muscle | origin or head |
| Muscles that work together | synergists |
| Sneering is accomplished by _________ | levator labii superiois |
| Muscle Fibers that are resistant to fatigue | Slow Twitch |
| The end of the muscle attached to the bone undergoing the greatest movement | Insertion |
| Group of muscles on each side of the back | Erector Spinae |
| Flexes the vertebral column | Rectus abdominis |
| flexes, extends, and abducts the arm | deltoid |
| Single sheet-like muscle that covers the anterolateral neck | Platsyma |
| Chest muscle that abducts and flexes the arm | Pectoralis major |
| The portion of the muscle between the origin and the insertion | Belly |
| Arm attached to the thorax by | Pectoralis major and lattimus dorsii |
| Attaches humeurs to the scapula | Rotators Cuff Muscle |
| Adducts the thigh | Adductor muscle |
| Forms the bulge of the calf | Gastrocnemius and soleus |
| Lateral muscle of the leg | Peroneus |
| flexes the wrist | Flexor Carpi |
| flexes the fingers | Flexor Digitorum |
| covers flexors and extensors and holds them in place | Retinaculum |
| Extends wrist | Extensor Carpi |
| Extends fingers | Extensor digitorum |
| Branch that conncts to muscle | Neuromusclar Junction |
| A muscle fiber will not respond to stimulus until that stimulus reaches a level called________ | Threshold |
| The sliding of action and myosin myofilaments during contraction is called _______ | sliding filament mechanism |
| The increase in number of motor units being activated is called_______ | recruitment |
| A single motor neuron and all the skeletal muscle fibers it innervates | motor unit |
| The spcae between the persynpatic terminal and muscle cell | Synaptic Cleft |
| An enlarged nerve terminal | Persynaptic terminal |
