lesson plan 11-12

Question 1

what is kinesiology?

Answer 1

science of movement

Question 2

what is biomechanics?

Answer 2

the application of mechanics to the living human body

Question 3

which of the following describes ‘linear motion’?

1. object progresses in a straight line with moving parts in the same direction
2. rotational motion on a central axis

Answer 3

1. object progresses in a straight line with moving parts in the same direction

Question 4

define longitudinal muscle fiber alignment

Answer 4

fibres run parallel blending together with the tendon. they don’t generate much tension and make up most upper body extremities

Question 5

what are example of longitudinal fibres?
( muscles and types )

Answer 5

parellel / fusiform
rhomboids / digastric / sternohyoid are some examples

Question 6

what are the type of penniform fibres?

Answer 6

unipennate (extensor digitorum longus)
bipennate (rectus femoris)
multipennate (deltoid)

Question 7

what is the major contributor to a particular movement, other muscles would be secondary agonist or assistant movers?

Answer 7

prime mover (agonist)

Question 8

what is the action opposite to the agonist that does not mean that they are exerting tension when the agonist contracts?

Answer 8

antagonist movement

Question 9

what is the voluntary fixation on isometric contraction of opposing muscle groups to ‘fix’ a joint in a position.

Answer 9

fixators

Question 10

do fixators decrease circulation which slows healing and attempt to protect the injuries area or muscle by fixing its position?

Answer 10

yes

Question 11

what is the two muscles which act together to produce a movement which neither could produce alone?

example: dorsiflexion by tib. anterior and extensor digitorum longs.

Answer 11

conjoint synergist

Question 12

what is neutralizing / counteracting synergists?

Answer 12

when a muscle crosses more then one joint it may produce a desirable movement at one joint but often produces an undesirable movement at other joints it crosses.

Question 13

what is the stabilizing of Proximal joints to help distal segments move effectively?

Answer 13

stabilizing synergist

Question 14

what is the CONTRACTION of a muscle that is insufficient due to limitations of muscle length?

Answer 14

active insufficiency

Question 15

what is the RANGE of motion insufficient due to limitations of muscle length?

Answer 15

passive insufficiency

Question 16

which class lever is most common?

Answer 16

3

Question 17

what is the fulcrum?

Answer 17

fixed point or joint

Question 18

are fast levers stronger or weaker?

Answer 18

weaker then slow levers

Question 19

what is the middle force in first class levers?

Answer 19

fulcrum

Question 20

what is the middle force in second class levers?

Answer 20

load

Question 21

what is the third class middle force?

Answer 21

effort or force

Question 22

what is a pair of scissor an example of? (lever)

Answer 22

first class lever

Question 23

what is a hockey stick an example of? (lever)

Answer 23

third class lever

Question 24

what is a wheel barrow an example of? (lever)

Answer 24

second class lever

Question 25

give an example of a body lever for each class

Answer 25

first class: gastrocs at the ankle no second class third class: bicep curls

Question 26

what is the law of the body remaining at rest or in a state of uniform motion in a straight line until acted upon by an unbalanced or outside force?

Answer 26

newtons first law of inertia

Question 27

what is inertia?

Answer 27

property of matter that causes it to resist any change of motion in either speed or direction

Question 28

what is newtons second law of acceleration?

Answer 28

the acceleration of a body is proportional to the force imparted to it and inversely proportional to its mass force/mass

Question 29

what is moment arm?

Answer 29

distance between the perpendicular line of force application to the axis of the lever

Question 30

what is resistance arm?

Answer 30

distance between the perpendicular of the line of resistance application to the axis of the lever

Question 31

when pushing a heavy box and the object pushes against the person or pulls down with equal force in opposite direction is an example of what newton law?

Answer 31

action reaction 3rd law

Question 32

a soccer ball is at the top of a field with no movement. a player kicks it towards the other side. what Law is this an example of?

Answer 32

inertia law one

Question 33

hitting a golf ball with a weight of 12lbs is an example of what law?

Answer 33

acceleration law two hitting the ball is force, the weight is the mass

Question 34

muscles around the scapula stabilize allowing to act as a stable base while the muscles move the glenohumeral joint is an example of what?

Answer 34

stabilizing synergist

Question 35

normally finger flexion used when gripping results in unwanted wrist flexion which must be counteracted by wrist extensors to neutralize this undesirable movement is an example of what?

Answer 35

neutralizing or counteraction synergist
