5.1 Anatomy of the Muscular System: Intro

Question 1

Which two systems work together to provide movement for the human body?

Answer 1

muscular and skeletal

Question 2

What are the three types of muscular tissue?

Answer 2

skeletal
smooth
cardiac

Question 3

Which muscle tissue is under conscious control?

Answer 3

skeletal

Question 4

What does it mean to be under conscious control?

Answer 4

a person can consciously decide to use the muscles to complete an action

Question 5

Where does communication within the body to coordinate movement begin?

Answer 5

brain

Question 6

What nerves carry signals from the CNS to a specific muscle to provide movement?

Answer 6

peripheral nerves

Question 7

What makes up the central nervous system?

Answer 7

brain and spinal cord

Question 8

What are motor actions?

Answer 8

messages from CNS to a muscle

Question 9

What is a sensation/sensory input?

Answer 9

when nerves carry information from the external environment to the CNS

Question 10

What combines to form complex networks of peripheral nerves throughout the body?

Answer 10

spinal nerves

Question 11

What are tendons?

Answer 11

connective tissue that connects skeletal muscle to bone

Question 12

What are the three functions of tendons?

Answer 12

flexible
bend at joints
cushion joints against sudden movement

Question 13

What are ligaments?

Answer 13

connective tissue that connects bone to bone

Question 14

What is the function of ligaments?

Answer 14

stabilize joints where bones meet

Question 15

What three things do all skeletal muscles have?

Answer 15

origin
insertion
action

Question 16

What is the origin of skeletal muscles?

Answer 16

bony site of attachment that is stationary during movement

Question 17

What is the insertion of skeletal muscle?

Answer 17

bony site of attachment that is moved by muscle contraction

Question 18

Which parts of skeletal muscle can be reversed during different types of movement?

Answer 18

origin
insertion

Question 19

For this module, how are we going to make standard origin and insertion points?

Answer 19

referenced from Anatomical position

Question 20

What is the action of a skeletal muscle?

Answer 20

what effect is produced by the muscles contraction
