1 Catalyst Hope you had a great Spring Break! 1.Sit at your assigned table. 2.Take out the work you completed with the substitute on Monday and Tuesday.

2 Agenda Catalyst Opening/Objective Lesson: Nervous System Open-Ended: Work Time

3 Announcements Midterm Assessment ▫April 8 th and 9 th (Tuesday and Wednesday) ▫Open-note (as always) ▫Cumulative  Includes all information covered this quarter :  Integumentary system  Muscular system  Skeletal system  Nervous system  Most of the questions should be familiar to you, so be sure to look over any areas that gave you problems on previous exams.  I will post the correct answers to past exams on the “Answer Board” by Monday

4 The Nervous System: Part I Focus on the Central Nervous System

5 Components Human Nervous System Central Nervous System Peripheral Nervous System Somatic Nervous System Autonomic Nervous System Sympathetic Nervous System Parasympathetic Nervous System

6 Central Nervous System Human Nervous System Central Nervous System Peripheral Nervous System Somatic Nervous System Autonomic Nervous System Sympathetic Nervous System Parasympathetic Nervous System

7 Central Nervous System Main Components: the brain and the spinal cord ▫Both are covered by the meninges (three layers of connective tissue) Functions: Processes information from the peripheral nervous system and sends signals back

8 The Brain Forebrain Midbrain Hindbrain

9 The Forebrain Cerebrum: higher brain function; thought and action 1.Frontal Lobe: reasoning/problem-solving; judgment; impulses; motor control; memory 2.Parietal Lobe: processes pain and touch sensation; cognition (mental activities) 3.Occipital Lobe: visual sensation and processing 4.Temporal Lobe: processes sound and language; emotion; memory; and speech

10 The Forebrain Thalamus: sends signals to other parts of the brain; motor control Hypothalamus: temperature; apetite; thirst; sleep Cerebral Cortex: “grey matter”; covers the cerebrum and cerebellum; processing information Corpus Callosum: connects the two hemispheres (halves) of the brain

11 The Forebrain Limbic System: emotions; motivation; emotional ties to memory ▫Hippocampus: short- and long-term memory indexing (processing); affected severely by Alzheimer’s disease ▫Amygdala: conditioned learning, especially fear/anger/rage ▫Olfactory Bulb: sense of smell; connected to amygdala  That’s why scents can bring back vivid memories!

12 The Forebrain Pituitary Gland: growth during childhood; temperature; thyroid function; urine production; testosterone production in males and ovulation/estrogen production in females Pineal Gland: controls sleep/wake cycles via melatonin production

13 The Midbrain Portion of the Brainstem: connects the forebrain and hindbrain ▫Involved in auditory and visual responses; motor function

14 The Hindbrain Pons: arousal, consciousness, and sleep Cerebellum: controls movement; posture; balance Medulla Oblongata: automatic functions like breathing, heart rate, and digestion

15 Spinal Cord Cylindrical bundle of nerve fibers that connects to the brain
