muscular system and muscles

Question 1

types of muscle

Answer 1

skeletal, cardiac, smooth

Question 2

striated muscle

Answer 2

skeletal and cardiac

Question 3

unstriated

Answer 3

smoth

Question 4

somatic nervous system control

Answer 4

skeletal muscle

Question 5

autonomic nervous system control

Answer 5

caridac and smooth muscle

Question 6

muscle functions

Answer 6

produce movement, maintain posture + body poistion, stabilise joints, generate heat

Question 7

muscle properties

Answer 7

electrical excitability, contractility, extensibility, elasticity

Question 8

wrapping of fibre (individual muscle cell)

Answer 8

endomysium

Question 9

wrapping of fascicle (bundle of individual muscle cells)

Answer 9

perimysium

Question 10

wrapping of whole muscle

Answer 10

epimysium

Question 11

muscle fibre

Answer 11

individual muscle cell

Question 12

fascicle

Answer 12

bundle of individual muscle cells

Question 13

whole muscle composition

Answer 13

individual muscle cells, blood vessels, nerves

Question 14

patterns of fascicle arrangement

Answer 14

circular, convergent, parallel, pennate

Question 15

types of parallel muscle

Answer 15

straplike and spindle shaed/fusiform

Question 16

types of pennate muscle

Answer 16

unipennate, bipennate, multipennate

Question 17

connective tissues associated with muscle

Answer 17

ligaments, tendon, aponeurosis, raphe

Question 18

ligaments

Answer 18

-fibrous connections between bones
-composed of collagen fibres
-usually blend with periosteum of bones at joint

Question 19

tendon

Answer 19

fibrous tissue, linking muscle belly tro attachment site at bone

Question 20

aponeurosis

Answer 20

-broad, flat connective tissue
-links muscle belly to site of attachment
-spread over greater area than tendon

Question 21

raphe

Answer 21

line of fibrous tissue, one muscle joins another (usually long)

Question 22

types of muscle contraction

Answer 22

isometric, concentric, eccentric

Question 23

prime mover

Answer 23

main muscle that produces specific movement (concenric contraction)

Question 24

synergist

Answer 24

compliment actions of prime mover

Question 25

ways synergist interact with prime mover

Answer 25

-add extra force to same movement -reducing undesirable/unnecessarhy movements

Question 26

antagonist

Answer 26

-opposes action of another muscle (eccentric contraction) -can regulate prime mover by providing resistance -> slow/stop movement

Question 27

fixator

Answer 27

steadies proximal parts of limb, when movements occur in distal parts (isometric contraction)

Question 28

superficial fascia

Answer 28

loose subcutaneous tissue

Question 29

deep fascia

Answer 29

thin rough sheet, primarily collagen fibres

Question 30

fascial septum

Answer 30

extension of dense connective tissue

Question 31

retinaculum

Answer 31

thickening of deep fascia, holds down tendons

Question 32

hilum

Answer 32

entry point for blood vessels/nerves to enter muscle
