Human Body Systems Group #4 - Control The Nervous System The Senses System The Endocrine System
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)
The Nervous System - Structures Cells – neurons (nerve cells) Tissue - nervous tissue Organs Brain Spinal cord
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
The Nervous System - Interactions Respiratory – controlled by the brain Cardiovascular – controlled by the brain Lymphatic – controlled by the brain Immune – controlled by the brain
The Senses - Functions Receive, carry, and send messages between the body, the spinal cord, and the brain
The Senses - Structures Cells – nerve cells Tissues – nervous tissue Organs Eyes – vision Ears – hearing and balance Skin – pressure and temperature Nose – smell Tongue - taste
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
The Senses - Interactions Respiratory – carries out directions from the brain Excretory – carries out directions from the brain Endocrine – carries out directions from the brain
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
The Endocrine System – Structures Cells – epithelial cells Tissues – epithelial tissue embedded within surrounding connective tissue
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
The Endocrine System – Interactions Cardiovascular – hormones transported by blood stream; hormones help regulate blood pressure and heart rate Digestion – regulates blood sugar & calcium
The Endocrine System – Interactions Nervous & Senses – communicates with brain to control body
