The muscular system

Question 1

Aponduroses

Answer 1

Broad sheets of connective tissue that can connect muscles to each other

Question 2

Fascia

Answer 2

Layers of dense connective tissue that surround and separate each muscle.

Question 3

Epimysium

Answer 3

The layer of connective tissue around each skeletal muscle

Question 4

Perimysium

Answer 4

Surrounds bundles of skeletal muscle fibres within each tissue

Question 5

Endomysium

Answer 5

A connective tissue layer that covers each muscle cell.

Question 6

Fasciles

Answer 6

Bundles of skeletal muscle fibres

Question 7

Muscle fibre

Answer 7

A single, long, cylindrical muscle cell.

Question 8

Sarcolemma

Answer 8

Cell membrane of a muscle cell

Question 9

sarcoplasm

Answer 9

cytoplasm of a muscle cell

Question 10

sarcoplasmic reticulum

Answer 10

The endoplasmic reticulum of the muscle cell

Question 11

neurotransmitter junction

Answer 11

A synapse between a motor neuron and a muscle fibre that it regulates.

Question 12

Fatigue

Answer 12

When a muscle loses its ability to contract during strenuous exercise.

Question 13

Threshold stimulus

Answer 13

The minimum strength of stimulus required to generate an impulse through a muscle fibre, release calcium ions, activate cross-bridges, and contract the muscle.

Question 14

Myogram

Answer 14

The recording of an electrically stimulated muscle contraction.

Question 15

Latent period

Answer 15

The brief delay between the stimulation and beginning of the contraction

Question 16

isotonic contraction

Answer 16

involves shortening of the muscle and is associated with movement

Question 17

isometric contraction

Answer 17

involves force generation without shortening and is used to resist overstretching and oppose gravity.
