How does the Body Communicate Internally?
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.
Nervous System
Network of neurons Neurons – cells that specialize in
receiving and transmitting information through the body
Split into Central and Peripheral Nervous System
Structure of the Neuron

Neurotransmitters
Biochemical substances that stimulate or suppress other neurons
Imbalances can cause major disorders
Ex: Dopamine, Serotonin
Peripheral Nervous System
Connects the Central nervous system to the rest of the body
Split into Autonomic and Somatic Nervous Systems
Autonomic Nervous System
Part of Peripheral Nervous System Sends messages to internal organs Coordinates functions of internal
organs Ex: respiration or digestion
Somatic Nervous System
Part of Peripheral Nervous System Send messages to body’s muscles
This is what allows you to text
Endocrine System
Endocrine glands release hormones into the bloodstream where they affect a wide array of bodily functions and behaviors
They coordinate with the nervous system
Endocrine System
Pituitary gland (master gland) – receive messages from the hypothalamus to stimulate or inhibit the release of other glands hormones

Endocrine System
Thyroid Issues: Underactive – lack of energy, weight gain, dry
skin or hair Overactive- Increased nervousness, rapid heart
beat, weightloss
Endocrine System
Pancreas Issues: Type 2 Diabetes Pancreatitis▪ Flu-like symptoms, Weight decrease, rapid
pulse
Frontal Lobe
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)
Parietal Lobe
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
Occipital Lobe
Processes vision and sensations from the eyes Color, movement,
shape, shading, and face recognition
Hemisphere Specialization

Hemisphere SpecializationAREAS 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
Hemisphere Activation Activity
Students should separate into pairs and choose one person to be the observer.
Questions 1-4
Involved left hemisphere functions (verbal, math, analytic)
Trend- eye movements to the right when processing the question
Questions 5-8
Involved right hemisphere functions (nonverbal, spatial, holistic)
Trend – eye movement to the left from processing
