Definition
| These are epithelial membranes that line body cavities and are usually able to perform functions such as absorption or excretion. |
|
|
Term
| Describe cutaneous membranes. |
|
Definition
| These are dry epithelial membranes that are often made up of layers of keratinized cells that make up the outermost protective boundary of the body. |
|
|
Term
| Describe serous membranes. |

Term
| What makes up the Peripheral Nervous System? |
|
Definition
| This is made of the nerves that run throughout the body such as down the arms and legs. |
|
|
Term
|
Definition
| A neuron is made up of a cell body, dendrites, and an axon. The cell body contains the nucleus. The dendrites are fibers that receive messages. the axon is a long structure that sens messages on to other neurons. |

|
|
Term
| What is the role of the cerebrum? |
|
Definition
| This is the outermost structure of the brain and has the role of processing thought such as those related to language, memory, and voluntary movement. |
|
|
Term
|
Definition
| These are nerves which carry messages from the body to the brain. These will indicate sensations of pain, pressure, and temperature. |
|
|
Term
|
Definition
| These are nerves which carry response messages from the brain to different parts of the body that cause the body to act. |

|
Term
|
Definition
| This is striated (striped) and branched, involuntary muscle that is found in the heart. |
|
|
Term
| Describe Skeletal Muscle. |
|
Definition
| This is striated (striped) and voluntary muscle that moves the bones of our body. |
|
|
Term
|
Definition
| This is unstriated, involuntary muscle that is found in places such as the digestive tract. |
|
|
Term
| What is the sliding filament theory? |
|
Definition
| This describes how myosin slides along actin when a muscle cell contracts. |
|
|
Term
| What chemical substance is released into the synaptic cleft between the nerve and the muscle to transmit the impulse causing the muscle to contract. |
|
Definition
| Neurotransmitter (Such as ACh) |
|
|
Term
| What is it called when a muscle is unable to contract? |
|
Definition
|
|
Term
|
Definition
| This is when the muscle remains in contraction. |

|
Term
| What happens when the number of muscle fibers contracting is increased? |
|
Definition
| The muscle force also increases |
|
|
Term
| What is meant by muscle origin? |
|
Definition
| This is where the muscle is attached to a non-moving bone. |
|
|
Term
| What is meant by muscle insertion? |
|
Definition
| This is where the muscle is attached to the moving bone. |
