Nervous System 1
The circular, dark opening in the center of the iris that lets light enter the eye.
What is the pupil?
A thin, light sensitive layer of tissue that lines the back inner wall of the eye.
What is the retina?
A snail-shaped, fluid-filled organ in the inner ear that converts sound waves into electrical signals for the brain.
What is the cochlea?
A clear, biconvex structure located directly behind the iris and the pupil.
What is the lens?
This is what the colored part of the eye is called.
What is the iris?
What we call sounds are actually these, being picked up by the ears and perceived by the brain.
What are vibrations (or waves)?
This part of the ear is filled with fluid and is lined with hair throughout.
What is the cochlea?
The two types of photoreceptors that can be found in the eye are these.
What are the rods and cones?
These substances are what allow two neurons or a neuron and an effector to communicate with one another.
What are neurotransmitters?
The type of drug that increases heart rate, blood pressure, and increase the rate of release of neurotransmitters is called by this term.
What is a stimulant?
In order for neurotransmitters to do their work, they must be released into these spaces, which would then allow two neurons or a neuron and an effector to communicate with one another.
What are synapses?
Specialized cells or nerve endings that detect physical or chemical stimuli from the external environment or within the body and convert them into electrical signals for the nervous system.
What is a sensory receptor?
The five main tastes that the tongue is able to sense are these.
What are sweet, salty, bitter, sour, and savory (or umami)?
Endorphins are produced by the brain and have many effects on the body. The effect that endorphins have that is mentioned in the book is this.
What is they act as pain killers?
Once a stimulant wears off, these are the possible results that the user can experience
What are fatigue and depression?
The formation of scar tissue in the liver due to prolonged alcohol use is called by this term.
What is cirrhosis?
Neurotransmitters are initially contained within these structures, which then fuse with the axon of the neuron so that the neurotransmitters can be released.
What are vesicles?
This question has two parts, and your team must get both to get credit for this question. The opium poppy produces this type of drug, which mimics a natural substance produced by the brain and is called by this term.
What is an opiate, and what is an endorphin?
The five categories of sensory receptors are these:
What are pain receptors, mechanoreceptors, chemoreceptors, photoreceptors, and thermoceptors?
