front 1 What are the functions of muscles? | back 1
|
front 2 What are myoepithelial cells? | back 2 They are mostly smooth muscle cells beneath the secretion cells(those secrete hormones, saliva, sweet,...)that control and regulate the release of secretion to the blood |
front 3 What are myofibroblast cells? | back 3 They are cells derived from mesenchymal Stem cells(Which are adult stem cells that can renew themselves and differentiate to make cells with specific jobs)that are related to healing muscles |
front 4 List properties of muscles. | back 4 Muscles are:
|
front 5 Which type of muscles are of the most in terms of quantity in humans? | back 5 Skeletal muscles |
front 6 What do you call No.1? | back 6 Perimysium |
front 7 What do you call No.4? | back 7 Fascicle |
front 8 What do you call No.5? | back 8 Endomysium |
front 9 What do you call No.6? | back 9 Epimysium |
front 10 What are the sites that muscles connect to? | back 10
|
front 11 Which one is the 'Sarcolemma'? | back 11 No.1 |
front 12 What do you call No.2? | back 12 Myofibril |
front 13 What do you call the nerves that stimulate muscles to contract? | back 13 Motor neuron |
front 14 What is Motor unit? | back 14 Its the combination of the motor neuron and all the muscles that it stimulates |
front 15 When do motor neurons end? | back 15 At the neuromuscular junction or "motor and plate" |
front 16 Muscle force depends on____. | back 16 The number of stimulated fibers |
front 17 Is the belly the strong part of the muscle? | back 17 No, it can't stand pressure or friction |
front 18 How do tendons get nutrition? | back 18 From the vessels of the muscles or the blood vessels of the periosteum |
front 19 What lubricates the tendons when they are subjected to friction? | back 19 Synovial bursa(synovial sheath) |
front 20 Where does capillary blood exchange happen in muscles? | back 20 In the endomysium of muscles |
front 21 What are muscle splinder and/or tendon splinders functions? | back 21 Its used for proprioception, to send signals about how long and how fast the muscle moved and become(to coordinate voluntary movement) |
front 22 What controls the blood vessel's walls of muscles? | back 22 The sympathetic fibers of nerves |
front 23 What happens to the muscles of a person the results in he/she getting paralysed? | back 23 The nerve trunk must be severed(cut off) |
front 24 What are types of muscle contraction? | back 24
Myofilaments(proteins in the myofibril) are sliding past each other(or in other words normal contraction where the muscles get shorter)
Contraction where muscles dont get shorter and tenstion in them increases |
front 25 What is muscle tone? | back 25 Amount of tension in a muscle |
front 26 Classify muscles based on their function. | back 26
|
front 27 Classify muscles based on how they got their name. | back 27 Muscles that got their name based on their:
Deltoids, Rhomboid
Major, miner, brevis, longus
Superspinatus, infraspinatus, Abdominis, oculi, temporalis
External and internal obliques, felxor D. Superficialis and felxor D. Profundus
Sternocledomastoid
Flexor, extensor and abductor |
front 28 What type of muscles dont get tired? | back 28 Smooth muscles |
front 29 What is unique about cadiact muscles that neither smooth nor skeletal muscles have it? | back 29 It can function in a steady rhythmic pace |
front 30 What is Muscular Dystrophy? | back 30 Its a Muscular system disorder that results in enlargement of muscles because of increased fat and connective tissue and at the same time degeneration of muscle fibers |
front 31 What type of people get Duchenne MD muscular system disorder? | back 31 People that lack the protein that maintain the sarcolemma |
front 32 What is Myasthemia Gravis muscle disorder? | back 32 Its a progressive weakness due to shortage of acetylochline receptors |
