Anatomy Muscles
| Question | Answer |
|---|---|
| shortens with force | Contractility |
| arm muscle | Biceps |
| Buttox | Gluteus Maxximus |
| skeletal muscle respond to a stimulus | Excitability |
| the ability to be stretched | Extensibility |
| after stretched it goes back to normal | Elasticity |
| connective tissue sheath surrounding skeletal muscle | epimysium |
| surrounds and separates muscle connective tissue located outside the epimysium | Fascia |
| thin thread of a natural or artificial substance | fibers |
| each fiber surrounded by a connective tissue sheath | endomysium |
| a threadlike structure, extends one end of a fiber to another | myofibrils |
| thin: represent 2 strands of pearls twisted | actin myofilaments |
| thick: represents bundles of golf clubs | myosin myofilaments |
| basic structure and functional unit of the muscle | sarcomeres |
| The charge difference across the membrane | resting membrane potential |
| a contraction of an entire muscle in response to a stimulus that causes the action potential in one or more muscle fibers | Muscle twitch |
| A muscle fiber will not respond to stimulus until that stimulus reaches a level | threshold |
| the beginning of a contraction | lag phase |
| the time of contraction | contraction phase |
| The time during which the muscle relaxes | relaxation phase |
| where the muscle remains contracted without relaxing | Tetany |
| The increase in number of motor units being activated | recruitment |
| without oxygen | Anaerobic respiration |
| the process of cellular respiration | Aerobic respiration |
| amount of oxygen needed in chemical reactions amount | oxygen debt |
| when ATP is used during muscle contraction faster than it can be produced in the muscle cells | Muscle fatigue |
| the length of the muscle does not change, but the amount of tension increases during the contraction process | isometric |
| the amount of tension produced by the muscle is constant during contraction | isotonic |
| the amount of tension produced by the muscle is constant during contraction | Muscle tone |
| contract quickly and fatigue quickly | Fast-twitch fibers |
| contract more slowly and are more resistant to fatigue | Slow-twitch fibers |
| (head) is the most stationary end of the muscle | origin |
| the end of the muscle undergoing the greatest movement | insertion |
| The portion of the muscle between the origin and the insertion | belly |
| Muscles that work together to accomplish specific movements | synergists |
| Muscles that work in opposition to one another | antagonists |
| one muscle plays the major role in accomplishing the desired movement | prime mover |
| raises the eyebrows. | Occipitofrontalis |
| closes the eyelids causes wrinkles in the skin at the lateral corners of the eye | Orbicularis oculi |
| puckers the lips | Orbicularis oris |
| flattens the cheeks. Trumpeter’s muscle | Buccinator |
| smiling muscle | Zygomaticus |
| sneering | Levator labii superioris |
| frowning | Depressor anguli oris |
| chewing | Mastication |
| lateral neck muscle and prime mover | Sternocleidomastoid |
| group of muscles on each side of the back | Erector spinae |
| elevate the ribs during inspiration | External intercostals |
| contract during forced expiration | Internal intercostals |
| accomplishes quiet breathing. Dome-shaped muscle. Aids in breathing | Diaphram |
| tendinous area of the abdominal wall | linea alba |
| each side of the linea alba | rectus abdominis |
| muscle is crossed by three fibrous bands | Tendinous inscriptions |
| rotates scapula | Trapezius |
| pulls scapula anteriorly | Serratus anterior |
| adducts and flexes the arm | Pectoralis major |
| medially rotates, adducts, and powerfully extends the arm | Latissimus dorsi |
| attaches the humerus to the scapula and clavicle | Deltoid |
| extends forearm and occupies the posterior compartment of the arm | Triceps brachii |
| flexes forearm and occupies the anterior compartment of the arm | Biceps brachii |
| flexes forearm | Brachialis |
| flexes and supinates the forearm | Brachioradialis |
| strong band of fibrous connective tissue that covers the flexor | Retinaculum |
| flexes the wrist | Flexor carpi |
| extends the wrist | Extensor carpi |
| flexes the fingers | Flexor digitorum |
| extends the fingers | Extensor digitorum |
| extends the leg; anterior thigh muscles | Quadriceps femoris |
| “tailors muscle”; flexes the thigh | Sartorius |
| posterior thigh muscles; flexes the leg and extends the thigh. | Hamstring muscles |
| form the calf muscle | Gastrocnemius and soleus |
| (Achilles tendon). Flex the foot and toes. | calcaneal tendon |
| The lateral muscles of the leg | peroneus |
| 20 muscles located within the foot | intrinsic foot |
