(hearts, diamonds, clubs, spades) Tuesday April 2, 2019 Agenda: Finish Nervous System and Introduce Endocrine System You will Need: Body Systems Workbook, Pencil, Highlighter, Lined Paper Turn in: Any missing work…Due Wednesday To DO: Create the following table on lined paper Task Time (Seconds) Trial 1 Trial 2 #1: 2 Piles #2: Red & Black Piles #3: 4 Piles #: 4 Piles (hearts, diamonds, clubs, spades)
I will learn the function of and components of the endocrine system. Learning Target: I will learn the function of and components of the endocrine system. Success Criteria: I can explain the function of the endocrine system and the identify the components of the endocrine system.
Daily Agenda Good Things Rater Check in Worth the Wait forms due—Friday April 26 Quizizz—Nervous, Endocrine and Integumentary Systems—Thursday April 4 (Open Note) Finish Notes—Nervous System pgs. 30-31 Activity—Stimulus and Response of the Nervous System Endocrine System Video LAUNCH
Two Divisions of the Nervous System Central Nervous System- brain and spinal cord
Two Divisions of the Nervous System Central Nervous System- brain and spinal cord Three Main Parts of Brain: Cerebrum- interprets input from senses and controls voluntary muscles
Two Divisions of the Nervous System Central Nervous System- brain and spinal cord Three Main Parts of Brain: Cerebrum- interprets input from senses and controls voluntary muscles Cerebellum- coordinates actions of muscles and helps keep your balance
Two Divisions of the Nervous System Central Nervous System- brain and spinal cord Three Main Parts of Brain: Cerebrum- interprets input from senses and controls voluntary muscles Cerebellum- coordinates actions of muscles and helps keep your balance Brainstem- controls homeostasis and coordinates involuntary muscles
What is this part of the brain called? Cerebrum Cerebellum Brain stem Spinal cord
What is the function of the brain stem? Controls homeostasis & voluntary muscles Controls senses & voluntary muscles Controls balance & coordinates muscles Controls homeostasis & involuntary muscles
When you feel hungry, what function is your nervous system trying to carry out? Maintaining homeostasis Moving your body Sensing your environment Keeping your balance
NOT in your NOTES Two Divisions of the Nervous System Peripheral Nervous System- connects the Central Nervous System to the rest of the body
Two Divisions of the Nervous System Peripheral Nervous System- connects the Central Nervous System to the rest of the body Two Groups: Somatic nervous system- controls voluntary actions and input from senses (sound, sight, touch, etc.)
Two Divisions of the Nervous System Peripheral Nervous System- connects the Central Nervous System to the rest of the body Two Groups: Somatic nervous system- controls voluntary actions and input from senses (sound, sight, touch, etc.) Autonomic nervous system- controls homeostasis by regulating the heart, breathing, and digestion without conscious thought
Nerve cells are called neurons Impulse- a message carried by a neuron
Nerve cells are called neurons Impulse- a message carried by a neuron Synapse- the small space that an impulse jumps between neurons
Types of Neurons Sensory neurons: in the skin, muscles, joints, and organs that can sense pressure, temperature, and pain
Types of Neurons Sensory neurons: in the skin, muscles, joints, and organs that can sense pressure, temperature, and pain neurons in nose & tongue sense tastes and smells neurons in inner ear sense sounds rods and cones in eye sense sight
Types of Neurons Motor neurons: stimulate muscle cells throughout the body
Types of Neurons Motor neurons: stimulate muscle cells throughout the body includes muscles of the heart, diaphragm, intestines, and bladder
Types of Neurons Interneurons: connect other neurons
Types of Neurons Interneurons: connect other neurons all neurons in the central nervous system (brain, spinal cord) are interneurons
Reflex Reflex- an involuntary response to a stimulus (change in environment) that allows the body to respond quickly without thinking about it.
What is an impulse? A nerve cell A message carried by neurons The space between two neurons A reflex
What is this structure called? Axon Synaptic terminal Nucleus Dendrite
What does a motor neuron stimulate? Brain cells Sensory organs Muscle cells Sensory neurons
Which is not true about a reflex? It is a quick response. It is voluntary. It does not require conscious thought. It is a response to an external stimulus.
Nervous System Response Activity--Instructions 1. You will need to get in groups of 4. 2. Jobs per team: Card Sorter Observer Timer Data Recorder 3. Each Group Follows these Steps The card sorter will shuffle a full deck of cards. The observer should be positioned so that he/she can see the actions of the card sorter. Timer tells the card sorter to begin, the sorter will begin the activity. Observer will watch the card sorter and tell the timer when the card sorter has finished sorting cards. The timer will note the time in seconds. The data recorder will record the time. You will do each activity 2 times.
Nervous System Response Activity—Task Guide Task—Sort Cards into the following groups #1: 2 Piles #2: Red & Black Piles #3: 4 Piles #: 4 Piles (hearts, diamonds, clubs, spades) 1. Record all times in your data table. 2. Answer the following question on your paper: Thinking about your nervous system, why did your response time change?
Endocrine System
Do the right thing even when no one is looking. It’s called integrity.
