The Nervous System The Endocrine System The Brain

 We inherit traits from our parents through genes  Genes are made up of units of DNA that are our genetic makeup  They are assembled into Chromosomes: we have 46 (23 from each parent)

 All behavior can not be linked to genetics but some things can be like genetic disorders  Ex: Down Syndrome is caused by a fragment in the 21 st chromosome

 On your own, read “Choosing your Children’s Genes” on pg. 46.  After reading, answer the 4 questions in your packet.

1. There are two types of ways your body communicates internally. They are… - Through the nervous system -Through the endocrine system 2. The nervous system usually generates your first, quick response. 3. Your endocrine system is run by your hormones which act as transmitters to the brain.

 Network of neurons  Neurons – cells that specialize in receiving and transmitting information through the body  Split into Central and Peripheral Nervous System

 Made up of the brain and the spinal cord

 Connects the Central nervous system to the rest of the body  Split into Autonomic and Somatic Nervous Systems

 Part of Peripheral Nervous System  Sends messages to internal organs  Coordinates functions of internal organs  Ex: respiration or digestion

 Part of Peripheral Nervous System  Send messages to body’s muscles  This is what allows you to text

 Biochemical substances that stimulate or suppress other neurons  Imbalances can cause major disorders  Ex: Dopamine, Serotonin  Fill out the chart using the placards

 Endocrine glands release hormones into the bloodstream where they affect a wide array of bodily functions and behaviors  They coordinate with the nervous system

 Hypothalamus- part of the brain that directs activity in the endocrine system.

 Pituitary gland (master gland) – receive messages from the hypothalamus to stimulate or inhibit the release of other glands hormones

 Endocrine System and the Pituitary gland  Brain Pop

 Using pg. 57 in the text

 Thyroid Issues:  Underactive – lack of energy, weight gain, dry skin or hair  Overactive- Increased nervousness, rapid heart beat, weightloss

 Pancreas Issues:  Type 2 Diabetes  Pancreatitis ▪ Flu-like symptoms, Weight decrease, rapid pulse

 Involved in complex mental processes  Separated into 4 lobes

 Regulates coordinated movements

 Sets brains alertness level and warning system

 Pathway for neurons traveling to and from the brain

 Manages body internal state

 Regulate motor movement and cognitive abilities like planning and decision making  Personality  Motor Cortex- controls the body’s voluntary muscles  Motor speech area (Broca’s area)

 Process sensory information like touch, temperature, body position and pain  Right half communicates with the left side of the body – Left half communicates with the right side of the body

 Processes Sounds  Stores long term memories

 Processes vision and sensations from the eyes  Color, movement, shape, shading, and face recognition

AREAS OF LEFT-HEMISPHERE DOMINANCE:  Verbal functions (for right-handers and most left-handers), including spoken and written use of language, as well as logical analysis, problem solving, and mathematical computation AREAS OF RIGHT-HEMISPHERE DOMINANCE:  Nonverbal functions, including understanding spatial relationships (as presented, e.g., in jigsaw puzzles or maps), recognizing faces and interpreting gestures, perceiving and expressing emotion, and appreciating music and art

 1 volunteer

 Students should separate into pairs and choose one person to be the observer.

 Involved left hemisphere functions (verbal, math, analytic)  Trend- eye movements to the right when processing the question

 Involved right hemisphere functions (nonverbal, spatial, holistic)  Trend – eye movement to the left from processing
