The Nervous system
The components of the central nervous system
Brain and Spinal cord
The Somatic nervous system is responsible for
The voluntary movement of skeletal muscles
The cell body of the neuron is also called the
Soma
The brain is part of which division of the nervous system?
The central nervous system
What are the causes of brain trauma?
Head knocks, stroke, infection/inflammation, tumours
The components of the peripheral nervous system are
The motor and sensory neurons
The Somatic nervous system carries what information to the Central nervous system?
Sensory information
Which part of the neuron receives messages?
The dendrite
What are the three main sections of the brain?
Forebrain, midbrain and hind brain
What is Broca's aphasia?
Damage to Broca's area means production of speech is impacted. Speech is not fluent.
Damage to the spinal cord in the middle of the back causes
Paraplegia
The Autonomic nervous system is responsible for
Involuntary movements in the body
Which is faster, a reaction or a reflex. Explain why.
A reflex is faster as it bypasses the brain, only passing through the spinal cord.
Which section of the brain is responsible for higher order and critical thinking?
The forebrain
What is Wernicke's aphasia?
Damage to Wernicke's area results in problems with language comprehension. Speech is fluent but nonsense.
Damage to the spinal cord at the neck causes
Quadriplegia
Which nervous system controls the Sympathetic and Parasympathetic nervous systems?
Autonomic nervous system
What is the purpose of the myelin sheath?
It insulates the signal through the neuron
Which section of the brain is responsible for the support of bodily functions?
The hindbrain
How can aphasia be treated?
Speech therapy
Carpal Tunnel Syndrome is caused by damage to
The peripheral nervous system
Which system is stimulated in a Fight or Flight situation?
Sympathetic nervous system
The three types of neurons and their functions are
Sensory - carry signal from PNS to brain
Motor- carry signal from brain to effector muscle
Interneuron - carry signal between the sensory and motor neurons
What are the lobes of the cerebral cortex and their functions?
Frontal - Movement, language, planning, judgement, thinking processes
Temporal - processes auditory information
Parietal - processes sensory information
Occipital - processes visual information
Which area of the brain connects Broca's and Wernicke's areas and is responsible for linking words to meanings?
Geschwind’s territory
