Unit 3 Psychology Exam

communication network within the body, that has three functions: receive, process and respond

Controls and runs everything our body does

Carry messages from the brain to different parts of the body

Central nervous system and Peripheral nervous system

The main control center that consists of the brain and spinal cord

Helps the central nervous system communicate with the rest of your body

Responds to stimuli and transmit signal

Picks up information from other cells and transmit it to cell body

Transmit signals away from the cell body to other cells

Sensory Organs: ears, eyes, mouths, tongue and skin

Activation of effector organs (muscles and glands) produces a response

Lesson 2

This controls your thinking, emotions and voluntary movement

Controls Balance, coordination and movement

outer region of the cerebrum, containing sheets of nerve cells; gray matter of the brain

The area of the brain that produces hormones that control: Body temperature. Heart rate. Hunger. Mood

learning and memory

Connect the 2 halves of the brain

Lesson 3

When you five senses gather information and send it to your brain

the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events

The smallest amount of physical stimulation that is required to detect sensory input

The minimum difference in physical stimulation to detect sensory input

Lesson 5

Stimuli, Depressants, Opiates. and Hallucinogens

psychoactive drugs that affect perceptual experiences and evoke sensory images even without sensory input

MDMA(ecstasy), lysergic acid diethylamide(LSD), psilocybin, mushroom peyote and marijuana

Increase nervous system activity, in both mental and physical processes which include caffeine, Cocaine, methamphetamine and nicotine

drugs that reduce neural activity and slow body functions, which includes alcohol

Psychoactive drugs that reduce pain and produce a pleasurable feeling, which includes include heroin morphine and codeine

mind-altering substances that change the brain neurochemistry b activating neurotransmitter systems

Lesson 6

the regulation of biological cycles in regular daily patterns

Stage 1: Begins when sleepers drift off and is shown on EEG as theta waves Stage 2: breathing becomes more regular and sleepers become less sensitive to external stimulation. The EEG show burst of brain activity called sleep spindles and spikes called K-complexes Stage 3 and 4: Slow-wave sleep- in stages 3 and 4 of deep sleep sleepers are hard to awaken and EEGs reveal large regular delta waves

Rapid eye Movements, dreaming, and paralysis of motor systems; EEGs show beta wave activity, which is associated with an awake, alert mind.

the actual content of the dream

the hidden meaning of the dream

3 and 4

certain aspects of wakefulness are maintained during a dreaming state. A person becomes aware that they are dreaming.
