The Central Nervous System (CNS) includes the brain and the...
Spinal cord
Autonomic Nervous System
Sensory organs
Pain receptors
The Autonomic Nervous system includes the
CNS and PNS
Sympathetic and Parasympathetic Nervous System
Somatic and Sympathetic Nervous System
Sensory and motor Neurons
The sensory information from the eye is processed in the
Frontal Lobe
Occipital Lobe
Temporal Lobe
Parietal Lobe
The central sulcus seperates the
Cerebrum from the Cerebellum
Left hemisphere from the right hemisphere
Frontal lobe from the parietal lobe.
Temporal lobe from the frontal lobe
The sympathetic nervous systems
increases the rate of digestion
controls and regulates most body functions to slow down, conserve energy and relax
controls and regulates the nerve reflex arc for rapid response of involuntary movement
controls and regulates most body functions for stress and quick responses to danger
Motor Neurons that control voluntary movement are part of the
Central nNervous System
Autonomic Nervous System
Somatic Nervous System
Sympathetic Nervous System
Where does the interpretation and understanding of incoming sensory information from major sensory organ and the millions of receptors throughout the body
mostly in the cerebellum
mostly in the frontal lobe
mostly behind the frontal lobe
mostly in the spinal cord
Fine motor movement, balance posture and muscle memory is mostly controlled by
cerebellum
medulla oblongata
sensory organs
cerebral cortex
The most abundant cell types in the central nervous system cells provide support for and insulation between neuron found in the brains are
glial cells
rod cells
interneurons
motor neurons
While no one knows exactly, it’s safe to say humans have approximately how many nerves in the human body?
30-50
100-200
10,000 - 20,000
bilions
The speed of nerve impulse transmission for myelinated neurons is at speeds up to...
120 m/s
120 km/hr
1.2 m/s
the speed of of light (3.00 X 108 m/s)
A nerve is
an electrochemically sensitive cell that is has axons and dendrites
an enclosed, cable-like bundle of axons in the peripheral nervous system (PNS)
a tube that lets sodium ion travel through at high speeds from one part of the body to another
many 1000s neurons linked together in a linear form
The main function of an axon is
increase the cell's surface area
to regulate nutrient intact for the cell body
to receive signals from neighbouring cells
transmit action potential away from the cell body to an adjacent cell
The main function of sensory neurons is to
transmit a stimulus from a receptor cell to the CNS
transmit a stimulus from the CNS to a receptor cell
interpret the meaning of a stimulus that occurs in a a receptor cell
to detect a stimulus and generate a chemical change in a sensory organ
In what form does a nerve impulse travel from neuron to another
electrical signal
chemical signal
magnetic signal
ionic signal
Which system below would have the most direct ability to speed up the heart rate at the SA node of the heart
Optic nerves
Sympathetic nerve fibers
Parasympathetic nerve fibers
Motor nerve fibers of the Somatic Nervous System
The purpose of the myelin sheath of the axon of a neuron is to
protect the neuron from damage
speed up action potential in the neuron
slow down up action potential in the neuron
stop action potential from spreading
The corpus callosum is composed a thick band of myelinated nerve fibers between left and right hemispheres. Its main purpose would be to
promote the reflex arc
quickly transfer signal between the left and right hemisphere
quickly transfer signal between the frontal and occipital lobes
to move sensory information from both the eyes the right to the left brain
which of the following is not part of the hindbrain
pons
cerebellum
hypothalamus
medulla oblongata
What part of the brain controls autonomic (involuntary) functions such as breathing, heart and blood vessel function, digestion, sneezing, and swallowing.
Hypothalamus
Medulla Oblongata
Corpus Callosum
Hipocampus
A part of the plays important roles in the consolidation of information (learning) from short-term memory to long-term memory, and in spatial memory that enables navigation. As well is involved with emotion and motivation. It has the shape of a seahorse
Thalamus
Cerebellum
Hippocampus
Medulla oblongata
What part of the brain is number 1?
Pons
Cerebrum
Cerebellum
Medulla Oblongata
Which of the following is the correct order for the reflex arch (ie touching a hot stove or when doctor taps the knee with a rubber hammer)
sensory neuron - receptor - motor neutron - effector (muscle reacts)- spine (interneuron)
effector (muscle reacts)- motor neutron - spine (interneuron)- sensory neuron -receptor
receptor - sensory neuron - spine (interneuron) - motor neutron - effector (muscle reacts)
receptor - sensory neuron - spine (interneuron) - effector (muscle reacts)- motor neutron
the receptors responsible for taste (taste buds) and smell are
Mechanorecptors
Thermoreceptors
Chemoreceptors
Olfactory nerve
The photoreceptors called cones and rods responsible for detecting light and are found in the
Pupil
Retina
Optic nerve
Occipital Lobe
Neuroplasticity refers to
the inability of a neuron to conduct action potential
the ability for membrane (resting) potential to occur in a neuron
the ability of neurons of the brain to rapidly repair and regenerate
the ability of the brain to change so that a given function can be transferred to a different location in the brain
The Peripheral Nervous System (PNS) is composed of
sensors and effectors
motor neurons and interneurons
the somatic and the autonomic nervous system
the sympathetic and the parasympathetic nervous systems
Which of the following is NOT responsible for the protection of the brain
meninges
frontal lobe
temporal bone
cerebral spinal fluid
The dendrite
is a long extension of a neuron
conducts nerve impulses to the cell body
is the main information processing center of the nervous system
is something in the environment that directly influences the activity of a living organism
A change in the external environment that initiates an electrochemical impulse is known as a
synapse
response
stimulus
receptor
