Neuron parts
What part of a neuron receives signals from other cells?
Dendrites
What consists of the Brain and Spinal Cord?
Central Nervous system
What is another term for sensory, motor, and interneurons?
afferent, efferent, and associative
What part of the brain is responsible for muscle coordination, balance, posture, and muscle tone?
Cerebellum
How is Alzheimer’s Disease diagnosed?
Diagnosed only after death
What part of a neuron transfers signals to other cells and organs?
Axons
What does the Nervous system do?
Controls all voluntary and involuntary movement through transmitting electrical impulses (nerve impulses)
what is sensory?
Carries impulses from all parts of the body to the Brain/Spinal cord (change, touch, light, sound, into nerve impulses)
Which part of the brain regulates the autonomic nervous system, temperature, appetite, sleep, water balance, and emotions?
Hypothalamus
What does the nervous system control?
The nervous system controls all of the body's voluntary and involuntary movements through transmitting electrical signals
Which part of a neuron allows diffusion of ions?
Node of Ranvier
What is the Peripheral Nervous system?
It consists of all Nervous Systems/Nerves.
what is motor?
carries impulses to muscle glands (changes impulses into activation)
The cerebrum's outer part is arranged in what specific structures?
Convolutions or folds
What structures surround and protect the spinal cord?
Vertebrae
What are the main parts of a Neuron?
Dendrites, Axon, & Cell Body
What is the difference between the somatic and autonomic nervous system?
Somatic- controls voluntary movement
Autonomic- controls involuntary movement (heart rate)
What is interneurons?
Interneruons transfer signals between other interneurons
Which part of the brain stem connects to the spinal cord and regulates heartbeat, respiration, swallowing, coughing, and blood pressure?
Medulla oblongata
What’s the main structural difference between gray matter and white matter?
Gray matter: mainly cell bodies of neurons
White matter: axons covered with myelin sheath
What is the role of Myelin Shealth?
Increases the speed of signal transmission
What is the difference between the sympathetic and parasympathetic nervous system
Sympathetic- controls fight or flight
Parasympathetic- rest & digest
Which neuron carries signals from the body to the brain and spinal cord by turning touch, light, and sound into nerve impulses, and which neuron connects sensory neurons to motor neurons?
Sensory neuron and interneuron
What are the four lobes of the cerebrum responsible for reasoning, thought, memory, speech, sensation, sight, smell, hearing, and voluntary movement?
Parietal, temporal, occipital, and frontal
What are the three meninges layers an what order are they in?
Dura mater (outer), arachnoid membrane (middle), pisa matter (inner)
