2Skeletal, Muscular, and Nervous Systems
3Skeletal System
- ______ is a connective tissue that produces red
blood cells and white blood cells.
4 5Bones give your body _____and they protect your
_______ organs.
6 7There are four types of bones in your body. Name
them.
8- Long bones
- Short bones
- Flat bones
- Irregular bones
9Bones meet at _________ where they are attached
to each other and to muscles.
10 11Bones are attached to each other by ________.
12 13Muscles are attached to bones by ______.
14 15_____ coats the ends of bones where they meet at
a joint. This allows smooth movement between
bones.
16 17Cartilage can also be found on the____ ear and
the tip of your_____.
18 19Joints
20- ______ ______allow back-and-forth movement.
21 22_____ _____ joints allow circular motion.
23 24Some joints dont allow any movement like the
__________ joints in the skull.
25 26- This joint allows the bones to twist against each
other in a semicircle motion. - What is it called?
27 28- These joints actually glide together when they
move. - What are they called?
29 30- There are three types of muscles. Name them.
31 32True or False.
- Voluntary, smooth, and cardiac muscles all will
contract.
33 34- What do voluntary muscles do?
35Voluntary muscles move bones and support the
skeleton.
36_____ ______ are in the bodys organs and move
slowly, controlling bodily functions.
37 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 40 41- What connects all the tissues and organs of the
body to the brain?
42The nervous system connects all the tissues and
organs of your body to your brain.
43- Name the two parts of the nervous system.
44The nervous system consists of two parts the
central nervous system and the peripheral nervous
system.
45- What makes up the central nervous system?
46The central nervous system is made up of the
brain and the spinal cord.
47- What makes up the peripheral nervous system?
48The peripheral nervous system consists of the
sensory organs and the body nerves.
49 50Nerves are bundles of nerve cells, or neurons.
51- What receives and transmits signals to other
neurons?
52Neurons receive and transmit signals to other
neurons.
53 54The gap between the neurons is called the synapse.
55- What do we call the neurons in sensory organs?
56Sensory 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 61- What do we call the part of the neuron that
carries signals and transmits them to other
neurons?
