Muscular System
Chapter 9 Anatomy & Physiology
| Question | Answer |
|---|---|
| The type of muscle that is only found in the heart | Cardiac Muscle |
| this muscle consist of short, branching fibers that fit together in intercalated discs | Cardiac Muscle |
| The type of muscle that is found in the digestive tract, blood vessels, bladder, airways, and uterus | Smooth Muscle |
| The type of muscle that attaches bone and causes movement to the body | Skeletal Muscle |
| A skeletal muscle cell is called a | Muscle Fiber |
| A delicate connective tissue that covers each muscle fiber is called | Endomysium |
| muscle fibers that are grouped in bundles are called | Fascicles |
| A sheath of tougher connective tissue that encases the fascicles is called | Perimysium |
| a layer of connective tissue that surrounds the muscle as a whole and binds all the muscle fibers together is called | Epimysium |
| Connective tissue that surrounds the muscle outside the epimysium is called | Fascia |
| this lies between muscles | Deep Fascia |
| this resides just under the skin | Superficial Fascia |
| Muscle fibers that merge with the periosteum of the bone, forming a strong attachment is called | Direct Attachment |
| when the epimysium extends past the muscle as a tendon . the tendon then merges with the periosteum is called | Indirect Attachment |
| the plasma membrane surrounding each muscle fiber is called a | Sarcolemma |
| the cytoplasm of the a muscle cells is called | Sarcoplasm |
| long protein bundles that fill the Sarcoplasm is called | Myofibrils |
| the smooth endoplasmic reticulum of a muscle fiber that surrounds each myofibril is called | Sarcoplasmic Reticulum |
| Myofibrils consists of even finer fibers called | Myofilaments |
| thick myofilaments are made of a protein called | Myosin |
| thin myofilaments consist of protein called | Actin |
| A system of tubules that extend across the sarcoplasm is called | Transverse Tubules |
| A plate or disc that serves as an anchor point for thin myofilaments is called | Z-disc/ Z-line |
| the section between the z-discs is called a | Sarcomere |
| the neuron and all the fibers is stimulates is called a | Motor Unit |
| the minimum voltage needed to cause a muscle fiber to contract is called the | Threshold |
| when a fiber receives a stimulus at or above threshold, it responds after a brief lag by quickly contracting and then relaxing is called | Twitch |
| the phenomenon, in which each successive twitch contracts more forcefully the previous one is called | Treppe |
| the condition of rapid contraction with only partial relaxation is called | incomplete tetanus |
| if the impulses arrive so fast that the muscle cant relax at all between stimuli is called | Complete tetanus |
| this refers to the end of the muscle that attaches to the more stationary bone | Origin |
| the thick mid-section of the muscle is called | the belly |
| the end of a muscle that attaches to the more movable bone is called | Insertion |
| muscles that trigger movement is called | Prime mover |
| muscles that assist in movement are called | Synergists |
| muscles that balance movements are called | Antagonists |
| this muscle raises the eyebrows when glancing upward or showing surprise | Frontalis |
| A sphincter muscle that closes the eye when blinking or squinting | Orbicularis Oculi |
| this muscle draws the mouth upward when laughing | Zygomaticus |
| this muscle closes the mouth and purses the lips, such as when kissing | Orbicularis oris |
| this muscle assists in smiling and blowing | Buccinator |
| this muscle aids in closing the jaw | Temporalis |
| this muscle actually closes the jaw | Masseter |
| this muscle flexes the head | Sternocleidomastoid |
| this muscle extends the head and flexes the head from side to side | Trapezius |
| the muscles that lie superficially between ribs; elevates the ribs during inspiration | External intercostals |
| enlarges the thorax to trigger inspiration | Diaphragm |
| this muscle compresses the abdominal organs with aids in forceful expiration, vomiting, and defecation | External Oblique |
| the aponeuroses of muscles forming the abdominal wall meet in the mid line of the abdomen, where they form a tough band of connective tissue called the | Linea Alba |
| this muscle flexes the lumbar region of the spinal column to cause bending forward of the waist | Rectus abdominis |
| this muscle compresses the contents of the abdomen | Transverse Abdominis |
| this muscle stabilizes the spine and maintains posture, just like the external oblique muscles | Internal Oblique |
| this muscle abducts, flexes, and rotates the arm | Deltoid |
| this muscle flexes and adducts the upper arm, such as when climbing or hugging | Pectoralis Major |
| this muscle drives all forward-reaching and pushing movements | Serratus anterior |
| this muscle raises and lowers the shoulders | Trapezius |
| this muscle adducts the humerus | Latissimus dorsi |
| the four tendons that are connected to the scapula is called | the rotator cuff |
| the muscle that is the prime mover when flexing the forearm is called | Brachialis |
| the muscle that assists the brachialis when flexing the forearm | Biceps Brachii |
| the prime mover when extending the forearm | Triceps Brachii |
| helps the brachialis and the biceps brachii flex the forearm | Brachioradialis |
| this muscle allows the arm to pronate | Pronator muscles |
| this lies deep within the forearm near the elbow | Supinator muscle |
| muscles that flex the wrist is called | Flexors |
| this flexes the thigh and consists of the llicus and psoas major | Lliopsoas |
| the longest muscle in the body is called | the Sartorius |
| these muscles rotate and draw the thigh in toward the body | Adductor muscles |
| the most powerful muscle in the body that is the prim mover for knee extension | Quadriceps Femoris |
| a group of muscles that work to extend the thigh at the hip, flex the knee and rotate the leg is called | Hamstring |
| this muscle abducts and rotates the thigh outward | Gluteus medius |
| the bulkiest muscle in the body. located in the butt | Gluteus Maximus |
| this muscle lies beneath the other two gluteal muscles | Gluteus minimus |
