muscle fibre arrangment

Question 1

what are the three types of parallel muscles

Answer 1

strap
fuse-form
fan-shaped

Question 1

what does strap muscle sacrifice

Answer 1

strength for range of motion

Question 2

describe strap muscles

Answer 2

fibres that run longitudinally to the contraction direction

Question 3

what is an example of a strap muscle

Answer 3

sartorious

Question 4

describe fusiform muscle

Answer 4

wider and cylindrically shaped in centre and taper off at the ends

Question 5

what is an example of a fusiform muscle

Answer 5

bicep brachii

Question 6

what are the three type of pennate muscles

Answer 6

unipennate
bipennate
multipennate

Question 7

describe a unipennate muscle

Answer 7

muscle attached to tendon on oneside

Question 8

describe bipennate muscle

Answer 8

tendon in the middle and muscle attached to both sides

Question 9

describe multipennate muscle

Answer 9

lots of tendinous attachments, like overlapping feathers

Question 10

describe convergent muscle

Answer 10

converge from a exctensive origin thinning out into a tendinous attachment

Question 11

example of a convergent muscle

Answer 11

pectoralis major

Question 12

describe circular muscle

Answer 12

fascicles arranged in a concentric rings, usually found I openings/orifices around the body

Question 13

example of circular muscle

Answer 13

sphincter muscles

Question 14

do pennate muslces have good range of motion

Answer 14

no as they sacrafice range of motion for stength

Question 15

describe the fascicles of a pennate muscle compared to a parallel fascicles

Answer 15

pennate muscles have shorter and more muscle fibres, more densely packed and at an angle, where as parallel have less and longer fibres
