The Brain Flashcards
What are the 2 main sections of the nervous system?
The Central Nervous System and the Peripheral Nervous System.
What does the CNS include?
The brain and spinal cord
What can the peripheral nervous system be broken down into?
The somatic and autonomic nervous systems
What is the function of the SNS?
It is responsible for the conscious perception and voluntary motor response to a stimuli. however some somatic responses can be reflexes
What is the role of the ANS?
This is responsible for the involuntary control of the body to maintain homeostasis. for example controlling sweat glands when you’re too hot
What can the SNS be broken down into?
The sympathetic and parasympathetic nervous systems
What is the role of the Sympathetic nervous system?
This is responsible for the fight or flight responses, some examples of this are: Shutting down the digestive system to stop blood can focus on delivering oxygen to the muscles, increased breathing rates, sweating and pupil dilation
What is the role of the parasympathetic system?
This is responsible for the “rest and digest” system. And is responsible for calming the body down after a sympathetic response, for example: slowing the heart rate, increases intestinal and gland activity for digestion and relaxes muscles
What are the names for the 4
main lobes of the Brain?
The frontal lobe, parietal, occipital and temporal lobes
What is the location and function for the frontal lobe?
Is responsible for motor skills such as walking and kicking, cognitive functions, reasoning e.g. weighing up consequences, planning, problem solving and expressive language
What is the location and function of the parietal lobe?
Found in the middle of the brain and is responsible for processing tactile sensory information. including touch, pain and pressure. also responsible for some motor skills and orientation
What is the location and function of the occipital lobe?
Is found at the back of the brain and it is responsible for interpreting visual stimuli and info.
What is the location and function of the temporal lobe?
Is found at the bottom of the brain and is responsible for interpreting sounds and language as well as storing memories in the hippocampus. is also responsible for speech
What is the location and function of the cerebellum?
Is located under the brain and above the pons of the brain stem. it receives balance information from the inner ear sensory nerves and visual systems. it is responsible for learning motor skills, coordination and movement.
What are the 3 sections of the brain stem?
The midbrain, pons and medulla
