Brain & Nervous System
This division of the nervous system includes the brain and spinal cord
What is the Central Nervous System (CNS)?
These structures receive incoming signals from other neurons.
What are dendrites?
This neurotransmitter is strongly associated with reward and motivation.
What is dopamine?
These chemical messengers travel through the bloodstream to target cells.
What are hormones?
This hormone is primarily responsible for male reproductive development.
What is testosterone?
This lobe of the brain is responsible for vision.
What is the occipital lobe?
This insulating covering speeds up nerve impulse transmission.
What is the myelin sheath?
This neurotransmitter is the primary inhibitory neurotransmitter in the brain.
What is GABA?
This gland is often called the "master gland."
What is the pituitary gland?
This hormone helps maintain the uterine lining during pregnancy.
What is progesterone?
This part of the brain helps coordinate balance and movement.
What is the cerebellum?
This electrical charge is approximately -70 mV in a resting neuron.
What is the resting membrane potential?
A drug that mimics the action of a neurotransmitter is called this.
What is an agonist?
This hormone lowers blood glucose levels.
What is insulin?
These chemicals interfere with normal hormone signaling and regulation.
What are endocrine disruptors?
This division of the autonomic nervous system is activated during the "fight-or-flight" response.
What is the sympathetic nervous system?
During this phase of an action potential, sodium ions rush into the neuron.
What is depolarization?
A drug that blocks receptor activity is called this.
What is an antagonist?
This type of feedback mechanism helps maintain homeostasis by reversing changes.
What is negative feedback?
This chemical commonly found in plastics can mimic estrogen in the body.
What is BPA
This structure controls essential life functions such as breathing, heart rate, and blood pressure.
What is the brainstem?
This structure is the gap between two communicating neurons.
What is a synapse?
This process causes a person to need larger doses of a drug to achieve the same effect over time.
What is tolerance?
These hormones regulate metabolism/hunger.
What are Ghrelin and Leptin?
The life time egg to daily sperm production ration is this
