The nervous system #1
What is the nervous system?
a nerve transmits signals throughout the body
Name the 3 parts of the brain
cerebrum, cerebellum, brain stem
How does the Nervous System help us respond to stimuli?
allows us to respond to stimuli by transmitting electrical signals.
What is the role of the spinal cord in the Nervous System
a pathway for transmitting signals between the brain and the rest of the body
what is the number 1 organ for the nervous system?
the brain
What is the main function of the nervous system ?
To transmit and process information, enabling communication and coordination
How does the brain communicate with the rest of the body
communicates with the rest of the body through the spinal cord and peripheral nerves.
what are neuro transmitters
chemical messengers that transmit signals between neurons.
system responsible for involuntary actions
somatic
what is the biggest nerve in the body
The sciatic nerve
what are neurons and what is their role in the nervous system?
the basic units of the nervous system, transmitting electrical signals to communicate information between different parts of the body.
How do drugs affect the nervous system?
affect the nervous system typically work by interacting with neurotransmitters or receptors.
What is the centural nervous system (cns) composed of
consists of the brain and the spinal cord.
How does the Nervous System help us sense and respond to our environment
allows us to sense and respond to our environment through specialized receptors
how many nerves are in your face
two facial nerves
Describe the structure or a neuron
consists of a cell body, dendrites, and an axon.
what is neuro plasticity, how does it contribute to learning and memory
the brain's ability to reorganize itself by forming new neural connections.
How does the nervous system maintain homeostasis in the body?
regulating various bodily functions
what are the 7 organs of the nervous system
the spinal cord, the medulla, the pons, the cerebellum, the midbrain, the diencephalon, and the cerebral hemispheres
what nerve controls your eyesight
optic nerve
How does the process of synaptic transmission work?
involves the release of neurotransmitters from the presynaptic neuron into the synapse.
what are the two main divisions for the nervous system
divided into two main parts: the Central Nervous System and the Peripheral Nervous System
What is the role of the brain in the nervous system
controls our thoughts, emotions, movements and processes sensory information
what are the 10 main parts of the nervous system
Brain Spinal Cord Nerves Meninges Cerebrospinal FluidSense Organs Functions of the Nervous System.
What is the role of the basal ganglia in the nervous system, and how does dysfunction in this region contribute to movement disorders?
basal ganglia are a group of nuclei in the brain involved in motor control and coordination. Dysfunction in the basal ganglia, often associated with conditions like Parkinson's disease, can lead to movement disorders.
