Nervous System Flashcards
Give three functions of the medulla oblongata
- Pathway to brain
- Breathing and heartbeat
- Less important reflexes
Give the three functions of the cerebellum
- Co-ordinates movement
- Provides muscle tone
- Posture and balance
Name the four lobes of the brain
- Frontal
- Parietal
- Temporal
- Occipital
Give the function of the ventricle in the brain
Filled with cerebral-spinal fluid for cushioning
Which nervous system is responsible for fight and flight?
Sympathetic
Which nervous system is responsible for rest and digest?
Parasympathetic
Which part of the nervous system is responsible for maintaining homeostasis involuntary movement?
Autonomic
What part of the nervous system are voluntary movement and skeletal muscles associated with?
Somatic
What part of the nervous system are cranial nerves and spinal nerves associated with?
Peripheral
What part of the nervous system are the brain and spinal cord part of?
Central
What kind of therapy can be helpful for multiple sclerosis?
Physical therapy
What type of therapy can slow down the progression of Alzheimer’s?
Immunotherapy
Multiple sclerosis symptoms:
Fatigue
Vision problems
Muscle spasms
Alzheimer’s symptoms:
Decline in memory
Dementia
Loss of motor functions (late stage)
Multiple sclerosis:
Autoimmune disease
Genetically inherited
Environmental liked
Loss of myelin sheath surrounding neuron’s
Can’t conduct electrical impulse from neuron to neuron
Affect 20-40 year olds
What type of plaque builds up around the neurons in Alzheimer’s?
Amyloid
Alzheimer’s:
Auto immune disease
Genetically inherited
Build of amyloid plaque around neurons
Prevents correct transfer of electrical impulse
Affects 50+ year olds
Spinal cord function:
Pathway for impulses
Intergrative reflexes
Primitive reflexes
Brainstem functions:
Pathway to and from brain
Breathing and heartbeat
Less important reflexes like sneezing or coughing
What is the lower section of the brain stem before exiting the forsaken magnum?
Medulla oblongata
Where is the medulla oblongata?
Brainstem
What part of the nervous system is responsible for posture and balance?
Cerebellum
Which part of the nervous system is responsible for muscle tone?
Cerebellum
Which part of the nervous system co-ordinates voluntary movement?
Cerebellum
