MUSCLE fibres

Question 1

Fusiform

Answer 1

run at the length of the muscle belly, made for mobility, contract at long ranges, produce low force

EG: BICEPS

Question 2

Pennate

Answer 2

run at angles of the tendons, less mobility than fusiform

Question 3

uni pennate

Answer 3

run at one side of central tendon

Question 4

bi pennate

Answer 4

run at either side of the central tendon

Question 5

multi pennate

Answer 5

branch off from several tendons, more force produced.

EG: deltoid

Question 6

Radiate Muscles

Answer 6

comes out from the main tendon, strength and power while having mobility

EG: deltoid

Question 7

features of msucles

Answer 7

Nervous Control: nerve stimuli control muscle action

hypertrophy: Muscles grow in size with exercise

Atrophy: Muscles loss size and strength due to lack of exercise or disease

extensibility: Muscles can stretch when force is applied

Contractability: muscles contract and get thicker

Elasticity: muscles return to normal shape once stretched

Question 8

muscle fibre

Answer 8

contains, mitochondria, myoglobin, actin, myosin filaments, atp and proteins
