Skeletal, Muscular, and Nervous Systems
3
Skeletal System
  • ______ is a connective tissue that produces red
    blood cells and white blood cells.

4
  • Bone marrow

5
Bones give your body _____and they protect your
_______ organs.
6
  • support
  • protect

7
There are four types of bones in your body. Name
them.
8
  • Long bones
  • Short bones
  • Flat bones
  • Irregular bones

9
Bones meet at _________ where they are attached
to each other and to muscles.
10
  • Joints

11
Bones are attached to each other by ________.
12
  • ligaments

13
Muscles are attached to bones by ______.
14
  • tendons

15
_____ coats the ends of bones where they meet at
a joint. This allows smooth movement between
bones.
16
  • Cartilage

17
Cartilage can also be found on the____ ear and
the tip of your_____.
18
  • outer
  • tip

19
Joints
20
  • ______ ______allow back-and-forth movement.

21
  • Hinge joints

22
_____ _____ joints allow circular motion.
23
  • Ball-and-socket

24
Some joints dont allow any movement like the
__________ joints in the skull.
25
  • immovable

26
  • This joint allows the bones to twist against each
    other in a semicircle motion.
  • What is it called?

27
  • Pivot Joint

28
  • These joints actually glide together when they
    move.
  • What are they called?

29
  • Gliding joints

30
  • There are three types of muscles. Name them.

31
  • voluntary
  • Smooth
  • cardiac

32
True or False.
  • Voluntary, smooth, and cardiac muscles all will
    contract.

33
  • True

34
  • What do voluntary muscles do?

35
Voluntary muscles move bones and support the
skeleton.
36
_____ ______ are in the bodys organs and move
slowly, controlling bodily functions.
37
  • Smooth muscles

38
  • ______muscles make up the wall of the heart, pump
    blood to the rest of the body, and set the pace
    of the heartbeat.

39
  • Cardiac

40
  • Nervous System

41
  • What connects all the tissues and organs of the
    body to the brain?

42
The nervous system connects all the tissues and
organs of your body to your brain.
43
  • Name the two parts of the nervous system.

44
The nervous system consists of two parts the
central nervous system and the peripheral nervous
system.
45
  • What makes up the central nervous system?

46
The central nervous system is made up of the
brain and the spinal cord.
47
  • What makes up the peripheral nervous system?

48
The peripheral nervous system consists of the
sensory organs and the body nerves.
49
  • What are nerves?

50
Nerves are bundles of nerve cells, or neurons.
51
  • What receives and transmits signals to other
    neurons?

52
Neurons receive and transmit signals to other
neurons.
53
  • What is a synapse?

54
The gap between the neurons is called the synapse.
55
  • What do we call the neurons in sensory organs?

56
Sensory organs contain neurons called receptors.
57
  • What are automatic muscle actions?

58
Reflexes are automatic muscle actions.
59
  • What do we call the part of the nerve cell that
    branches out and receives signals from other
    cells?

60
  • Dendrites

61
  • What do we call the part of the neuron that
    carries signals and transmits them to other
    neurons?

62
  • Axons
