Nervous system
A group of parts that were together to function or perform a task.
System
The main control center in an animal body; part of the central nervous system
The Brain
An organism's reaction to a stimulus
Response
A term used to describe a nerve cell
Neuron
The basic building block of all living things
Cell
The system of the body that carries information to all parts of the body. It relies on nerve cells to move electrical signals to the body from the brain, and from the body to the brain, and or spinal cord
Nervous system
To act because of something that happened
React
A group of parts that were together to function or perform a task.
System
An automatic response
Reflex
A tiny structure within cell that performs a specific function for that cell
Organelle
A bundle of nerves that runs along the back of a vertebrate within the spinal column.
Spinal cord
The cell of the nervous system that carries signals to the body from the brain, and from the body to the brain and/or spinal cord
Nerve
The part of the brain that controls conscious thoughts, senses, language, and memories.
Cerebrum
The part of the brain that controls balance, coordination, and conscious muscle activities
Cerebellum
A stiff structure that surrounds and protects a cell; found in plant, fungus, and some bacteria cells
Cell wall
What are the two main parts of the nervous system?
The CNS and the PNS
Nerve impulses travel from one neuron to another to send and receive signals in the brain. The neurons do not touch each other. What is the term for the gap the signal has to cross between the neurons?
Synapse
What are the structures of the neurons?
Neurons have three main parts: the soma, which is the main body; the dendrite, which branches off the soma; and the axon, which extends the opposite direction away from the soma.
What is the function of the structures of the neurons?
Dendrites receive information passing it through the soma and axons send information.
What structures do most cells have in common?
Most cells have many structures in common. Included among these are cytoplasm, a cell membrane, a nucleus, mitochondria, ribosomes, and vacuoles.
What does the Central Nervous system include and what is it's function?
The CNS includes the brain and spinal cord, and it controls all of the body's functions. It sends messages between the brain, the spinal cord, and other parts of the body.
What does the Peripheral Nervous system include and what is it's function?
The PNS is the second part of the nervous system. It consists of all the nerves that branch out from the spinal cord to all parts of the body. It aids in sending, and receiving the messages to and from the brain.
How are nerve impulses sent throughout the body?
Neurons send information through the body by using electrochemical impulses. The body often gets stimulus, such as a sound, or a feeling, and this message is sent to neurons through the brain. The brain can then send a message back to that part of the body.
Wat is the essential question we have been trying to answer in this topic?
How do organisms live, grow, respond to their environment, and reproduce?
What is the difference between mitosis and meiosis?
Both are processes of cell division. Mitosis results in the division of one cell to form two cells identical to the parent cell. Meiosis results in the division of one cell to form four cells that each have one half of the number of chromosomes present in the parent cell.
