Flashcards in The Nervous System Deck (18)
What is the human nervous system decided into?
The central nervous system and the peripheral nervous system
What does the central nervous system consist of?
The brain and the spinal cord. It receives information from the senses and controls the body’s responses
What does the peripheral nervous system include and what is it ?
The somatic nervous system and the autonomic nervous system. It’s part of the NS outside the brain and spinal cord
What does the somatic nervous system do?
It is responsible for carrying sensory and motor information to and from the CNS
What does the autonomic nervous system do?
Governs the brains involuntary activities and is self-regulating.
What is the autonomic nervous system further divided into?
Sympathetic nervous system - flight or fight. Parasympathetic - rest and digest.
What are the four main areas of the brain?
The cerebrum, cerebellum, diencephalon and the brain stem.
What is the cerebrum
The largest part of the human brain, associated with higher brain function such as thought and action. The cerebral cortex is divided into four sections, called "lobes": the frontal lobe, parietal lobe, occipital lobe, and temporal lobe.
Frontal lobe is responsible for?
Functions such as speech, thought and learning.
Temporal lobe is responsible for?
Hearing and memory
Parietal lobe is responsible for?
Sensory information such as touch, temperature and pain
Occipital lobe is responsible for?
processes visual information
What does the cerebellum do?
Receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum also coordinates voluntary movements such as posture, coordination, and speech.
What does the diencephalon do?
Contains the hypothalamus - regulates body temperature, hunger and thirst.
Contains the thalamus - routes nerve impulses to the appropriate part of the brain where they can be processed.
What does the brain stem do?
Regulates automatic functions that are essential, (breathing etc)
What is the main function of the spinal cord?
Relay information between the brain and the rest of the body
How does the SNS help deal with emergencies?
Neurons from the SNS travel to every organ and gland within the body, preparing the psychology for rapid action.
