Answer the Firday Bellwork Question!
Close your eyes. What observations can you make about your environment with your eyes closed? (ex. Smell, temperature, texture, sound). Open your eyes and list 5 observations you can make about the classroom without using your eyes. How are you able to make those observations? Answer the Firday Bellwork Question! Bellwork

Bellwork Review We can make the observations because the nerves that run through our skin, our sense of hearing, and our sense of smell are all connected to the brain. Our nervous system collects information about the outside world and our brain processes the information.

objectives Students will be able to analyze how plant and animal cells are organized to carry on the processes of life. SPI Explain the basic functions of a major organ system. Success Criteria: I can describe the function of the nervous and endocrine systems. I can explain how they work with other systems.

Nervous System Demonstration
You will work with the person sitting next to you. One person will stand with their eyes closed and palm up while the other puts a small dot with a pen on the persons finger tip. WITHOUT OPENING THEIR EYES, the first person must try to touch the dot with their other hand. Repeat with the forearm and upper arm. Switch sides.

Nervous System (pg ) The nervous system acts as the body’s central command post. Two basic functions: Gather and interpret information from inside your body and from the world outside. Respond to that information as needed. Two parts of the nervous system: Central nervous system (CNS)- brain and spinal cord Peripheral nervous system (PNS)- connects all parts of the body to the CNS and uses nerves to carry information between your body and the CNS.
7
Nervous System (pg. 282-295) Peripheral Nervous System:
Messages about your environment travel through the nervous system along neurons. A neuron is a nerve cell that is specialized to transfer messages in the form of fast-moving electrical energy or impulses.
8
Nervous System (pg. 282-295) Peripheral Nervous System:
A nerve is a collection of nerve fibers (axons) through which impulses travel between the CNS and the other parts of the body. A message from the brain travels down the spinal cord, then along the axon of a motor neuron inside a nerve to the muscle. The message makes the muscle contract.
9
Nervous System (pg. 282-295) Central Nervous System:
The brain is the mass of nerve tissue that is the main control center of the nervous system. Three main parts of the brain: Cerebrum- largest part of the brain where you think and where most memories are stored; controls voluntary movements and allows you to sense touch, light, sound, etc. Cerebellum- second largest part of the brain that allows the brain to keep track of your body’s position, such as balance. Medulla- connects to your spinal cord and controls involuntary processes, such as blood pressure and heart rate.
11
Nervous System (pg. 282-295) Central Nervous System:
The spinal cord carries information to and from the brain. Vertebrae protect the spinal cord.

Function: The nervous system receives and sends electrical messages throughout your body. Major Organs: brain, spinal cord, nerves How it works with other systems: controls the other systems
14
Endocrine System (pg. 296-299)
The endocrine system is a collection of glands and groups of cells that secrete hormones that regulate growth, development, and homeostasis. A gland is a group of cells that make special chemicals for the body. A hormone is a chemical messenger that flows through the bloodstream to all parts of the body. Epinephrine (adrenaline) is released from the adrenal gland, which increases your heartbeat and breathing rate. When you are frightened, angry, or excited, this “fight-or-flight” response prepares you to fight the danger or run from it.

Function: Glands send out chemical messages in the form of hormones. Major Organs: pituitary gland, thyroid gland, adrenal glands How It Works with Other Systems The endocrine system sends chemical messages to the other systems to regulate the human body.
