Lobes of the Brain
Which lobe is situated towards the front of the brain?
Frontal lobe
Largest part of the brain
(cerebrum, cerebellum, diencephalon, corpus callosum or brain stem)
Cerebrum
Includes the brain and spinal cord.
Central Nervous System
Also known as the cell body
(axon, dendrite, soma and myelin sheath)
Which nerve root innervates the patella tendon?
L4
This lobe is located on the sides and is in charge of auditory functions.
Temporal lobe
Connects the left and right hemisphere of the cerebrum.
(cerebrum, cerebellum, diencephalon, corpus callosum or brain stem)
Corpus callosum
Which division contains motor neurons send messages from brain to skeletal muscles and glands.
Motor division
One, long projection on a neuron that sends the message away to the next neuron.
(axon, dendrite, soma and myelin sheath)
Axon
Areas of skin that send signals to the brain through the spinal nerves.
Dermatomes
This lobe is responsible for interpreting visual information and sits at the back of our brain.
Occipital Lobe
Allows "muscle memory" and muscle coordination
(cerebrum, cerebellum, diencephalon, corpus callosum or brain stem)
Also known as the afferent division of the nervous system.
Sensory Division
Many projections coming off of the soma in a neuron that receives electrical impulses from neighboring neurons.
Dendrites
Which nerve root innervates the achilles tendon?
S1
This lobe is at the top and middle portion, it is also known as our sensory cortex.
Parietal Lobe
Controls blood vessels dilation and constriction
(Thalamus, hypothalamus, medulla oblongata, pons, pituitary gland)
medulla oblongata
This division causes the body to "rest and digest".
Parasympathetic Nervous System
Insulates the axon of a neuron (makes sure electricity stays where it needs to be)
(axon, dendrite, soma and myelin sheath)
Myelin Sheath
Which division of the motor division of the peripheral nervous system causes involuntary movements?
Autonomic Nervous System
Lobe of the brain responsible for “executive function” – planning, organizing, & decision making.
Frontal Lobe
Controls other hormone releasing glands
(Thalamus, hypothalamus, medulla oblongata, pons, pituitary gland)
Pituitary gland
This division contains cranial nerves and spinal nerves.
Peripheral Nervous System
True or False: Neurons cannot be replaced.
True
What are the two divisions of autonomic nervous system?
Sympathetic and Parasympathetic Nervous Systems
