Ch.6 Muscle
| Question | Answer |
|---|---|
| The ability of skeletal muscle to shorten with force. | What is Contractility. |
| The capacity of skeletal muscle to respond to a stimulus. | What is Excitability. |
| The ability to be stretched. | What is extensibility. |
| Ability to recoil to their original resting length after they have been stretched. | What is elasticity. |
| Each skeletal muscle is surrounded by a connective tissue sheath called. | What is Epimysium. |
| Another connective tissue located outside the epimysium. It surrounds and separates muscles. | What is fascia. |
| Muscle composed of numerous visible bundles | What is muscle fascicle. |
| Muscle surrounded by loose connective tissue | What is Perimysium. |
| The fascicle are composed of single muscle cells | What is Fibers. |
| Muscle Cells | What is Muscle Fibers. |
| Buttocks | What is Gluteus Maximus. |
| Chest Muscle | What is Pectoral Muscle. |
| Anterior thigh muscle | What is Quadriceps Femoris. |
| Posterior thigh muscle | What is Hamstrings. |
| Top arm muscle | What is Bicep |
| Bottom arm muscle | What is Tricep |
| ATP | What is Adenosine Triphosphate |
| ADP | What is Adenosine Diphosphate |
| Creatine Phosphate | What is High-energy molecule |
| Anaerobic respiration | Without oxygen |
| Aerobic respiration | With oxygen (more efficient) |
| Isometric | (Equal Distance) - Amount of tension increases during the contraction process |
| Isotonic | (Equal Tension) - But the length of the muscle changes |
| Muscle tone | Keeps head up and back straight |
| Fast twitch fibers | Contract quickly and fatigue quickly |
| Slow twitch fibers | Contract more slowly and are more resistant to fatigue |
| Origin | Most stationary end of the muscle |
| Insertion | Muscle undergoing the greatest movement |
| Belly | Portion of muscle between the origin and insertion |
| Synergists | Muscles that work together to accomplish specific movements |
| Antagonists | Muscles that work in opposition |
| Occipitofrontalis | Raises the eyebrows |
| Prime Mover | Muscle that plays a major role among a group of synergists |
| Orbicularis oculi | Closes the eyelids and causes "crows feet" |
| Orbicularis oris | Puckers the lips |
| Buccinator | Flattens the cheeks |
| Orbicularis oris/ Buccinator | Kissing muscles |
| Zygomaticus | Smiling muscle |
| Levator labii superioris | sneering |
| Depressor anguli oris | frowning |
| Mastication | Chewing |
| Intrinsic tongue muscles | change the shape of the tongue |
| Extrinsic tongue muscles | move the tongue |
| Trapezius | Rotates scapula |
| Serratus anterior | pulls scapula anteriorly |
| Pectoralis major | Adducts and flexes the arm |
| Latissimus dorsi | Medially rotates, adducts, and powerfully extends the arm |
| Deltoid | Attaches the humerous to the scapula and clavicle |
| Triceps brachii | extends the forearm |
| Biceps brachii | Flexes the forearm, Occupies the anterior compartment of the arm |
| Brachialis | Flexes forearm |
| Brachioradialis | Flexes and supinates the forearm |
| Flexor carpi | Flexes the wrist |
| Extensor carpi | Extends the wrist |
| Flexor digitorum | flexes the fingers |
| Extensor digitorum | Extends the fingers |
| Sartorius | Flexes the thigh |
| Sliding filament mechanism | the sliding of actin myofilaments past myosin myofilaments during contraction |
| Muscle twitch | Contraction of an entire muscle in response to a stimulus |
| Threshold | muscle fiber will not respond to stimulus until that stimulus reaches a level |
| Lag phase | time between application of a stimulus to a motor neuron and the beginning of a contraction |
| contraction phase | time of contraction |
| Relaxation phase | time during which the muscle relaxes |
| Tetany | muscle remains contracted without relaxing |
| recuitment | increase in number of motor unit being activated |
