1. Human Body Systems Group #4 - Control
The Nervous System
The Senses System
The Endocrine System

2. The Nervous System - Functions
Controls the body’s development and function
Helps the body respond and adjust to the external environment
Helps the body internally with chemical balance
Conscious mind (voluntary, somatic)
Subconscious mind (involuntary, autonomic)

3. The Nervous System - Structures
Cells – neurons (nerve cells)
Tissue - nervous tissue
Organs
Brain
Spinal cord

4. The Nervous System - Interactions
Skeletal – controlled by the brain
Muscular – controlled by the brain
Integumentary (Skin) – contains nerve cells that sense pressure and temperature
Digestive – controlled by the brain

5. The Nervous System - Interactions
Respiratory – controlled by the brain
Cardiovascular – controlled by the brain
Lymphatic – controlled by the brain
Immune – controlled by the brain

6. The Senses - Functions
Receive, carry, and send messages between the body, the spinal cord, and the brain

7. The Senses - Structures
Cells – nerve cells
Tissues – nervous tissue
Organs
Eyes – vision
Ears – hearing and balance
Skin – pressure and temperature
Nose – smell
Tongue - taste

8. The Senses - Interactions
Skeletal – carries out directions from the brain
Muscular – carries out directions from the brain
Skin – senses the surroundings
Cardiovascular – carries out directions from the brain
Digestive – carries out directions from the brain

9. The Senses - Interactions
Respiratory – carries out directions from the brain
Excretory – carries out directions from the brain
Endocrine – carries out directions from the brain

10. The Endocrine System – Functions
Releases chemicals (hormones) that help direct the activities of the body to maintain proper function
Controls metabolism (chemical reactions) in the body
Helps control growth, development, and reproduction

11. The Endocrine System – Structures
Cells – epithelial cells
Tissues – epithelial tissue embedded within surrounding connective tissue

12. The Endocrine System – Structures
Organs – Glands
Hypothalamus – a main link between glands and the brain
Pituitary – another main link between the glands and the brain
Thyroid – controls rate of burning energy (metabolism)
Parathyroid – calcium regulation
Adrenal – control amounts of salt and water in body as well as stress response and response to disease
Pancreas – insulin for maintaining blood sugar levels
Pineal – regulates sleep cycle
Ovaries/Testes - reproduction

13. The Endocrine System – Interactions
Cardiovascular – hormones transported by blood stream; hormones help regulate blood pressure and heart rate
Digestion – regulates blood sugar & calcium

14. The Endocrine System – Interactions
Nervous & Senses – communicates with brain to control body
