Unit 1
This term refers to the genetic makeup passed down from one generation to the next.
What is heredity?
This part of the brain controls vital functions such as breathing and heart rate.
What is the medulla?
This part of the neuron receives incoming signals from other neurons.
What is the dendrite?
This gland is considered the "master gland" and controls other endocrine glands.
What is the pituitary gland?
The body's internal 24-hour cycle that regulates sleep, wakefulness, and other physiological processes.
What is circadian rhythm?
This debate concerns the relative influence of genetic factors versus environmental factors on development.
What is nature vs. nurture?
This system controls the network of nerves outside the brain and spinal cord. (Have to say full name, not just the initials!)
What is the Peripheral Nervous System?
This brief electrical charge travels down the axon in neural communication.
What is an action potential?
This hormone, produced by the adrenal glands, prepares the body for fight-or-flight responses.
What is adrenaline?
Stage of sleep where dreaming occurs.
What is REM sleep (Rapid Eye Movement)?
This chemical substance transmits signals across the synapse between neurons.
What is a neurotransmitter?
This brain structure acts as a relay station for sensory information.
What is the thalamus?
This insulates axons and speeds up neural transmission by allowing impulses to jump between nodes.
What is the myelin sheath?
This organ produces insulin and glucagon to regulate blood sugar levels.
What is the pancreas?
A class of drugs that speed up the brain and body. They can make a person feel more awake, alert, confident or energetic.
What are stimulants?
This is the gap between two neurons where communication occurs.
What is a synapse?
This brain structure coordinates voluntary movements and maintains balance.
What is the cerebellum?
This refers to the brain's ability to change and adapt based on experiences.
What is neuroplasticity?
It regulates bodily functions such as hunger, thirst, temperature, and emotional responses. It also controls the pituitary gland; the key to homeostasis
What is the hypothalamus?
A temporary inability to move or speak that happens as you're falling asleep or waking up, where your mind is conscious but your body remains unmovable, often causing fear and seeing figures that are not actually there.
What is sleep paralysis?
This long projection conducts electrical impulses away from the neuron's cell body.
What is an axon?
The autonomic nervous system consists of the sympathetic division and the other division; what is its name and what does it do.
These specialized cells transmit information via electrical and chemical signals, the basic unit of the nervous system.
What is a neuron?
This brain structure is involved in processing emotions and memory
What is the amygdala?
The affect of psychoactive drugs on neurotransmitters.
What is mimicking their effects, blocking their receptors, or increasing/decreasing their release or reuptake?
