The Nervous System Flashcards
What two parts is the nervous system composed of?
- Central Nervous system
- Peripheral Nervous system
what pathways is the peripheral nervous system split into two?
- Afferent pathways
- Efferent pathways
What systems is the Efferent pathway split into?
- Somatic Nervous system
- Autonomic nervous system
What further systems is the autonomic nervous system split into?
- Sympathetic Nervous system
- parasympathetic nervous system
What is the Sympathetic Nervous system responsible for?
- fight or flight
What is the parasympathetic nervous system responsible for?
- Rest and digest
What two parts is the central nervous system composed of?
- Brain
- Spinal Cord
What is the the peripheral Nervous system?
- Nerves that go from the CNS to organs in the body
What is the afferent pathway (sensory)?
- It is how the CNS receives information about stimuli
What is the Efferent Pathway (motor)?
- It is how the body reacts to stimuli
What two senses, organ and stimuli is the chemoreceptor responsible for?
- Sense: Smell
- Organ: tongue
- Stimulus: Chemical
- Sense: Taste
- Organ: nose
- Stimulus: Chemical
What sense, organ and stimuli is the photoreceptor responsible for?
- Sense: Sight
- Organs: Eyes
- Stimulus: Light-photos
What sense, organ and stimuli is the Mechanoreceptor responsible for?
- sense: Sound
- Organ: Ear
- Stimulus: Sound/vibrations
What sense, organ and stimuli is the Thermoreceptor responsible for?
- sense: Touch
- Organ: skin
- Stimulus: Heat/thermal
What sense, organ and stimuli is the Nocireceptor responsible for?
- sense: Touch
- Organ: skin
- Stimulus: Pain
What sense, organ and stimuli is the Mechanoreceptor responsible for? (hint:touch)
- sense: Touch
- Organ: skin
- Stimulus: pressure/vibrations
What is the sensory nervous system ‘s role?
- Voluntary and reflex
- Nerve impulses from CNS to muscles
What is the Autonomic nervous system ‘s role?
- Involuntary (mostly)
- Nerve Impulses from CNS to heart, muscle, glands, digestive system etc
What is the speed of the response for a Sympathetic nervous system?
- fast response
What is the breathing rate for a Sympathetic nervous system?
- High breathing rate
What is the speed of the response for a Parasympathetic nervous system?
- slow response
What is the breathing rate for a parasympathetic nervous system?
- Low breathing rate
What is the breathing rate for a Sympathetic nervous system?
- high heart rate
What is the Heart rate for a parasympathetic nervous system?
- low heart rate
What is the blood flow to muscles for a Sympathetic nervous system?
- fast blood flow to muscles
What is the breathing rate for a Sympathetic nervous system?
- slow blood flow to muscles
What is the blood pressure for a Sympathetic nervous system?
- fast blood pressure
What is the blood pressure for a parasympathetic nervous system?
- slow blood pressure
What is the digestive function for a Sympathetic nervous system?
- slower digestive function
What is the digestive function for a parasympathetic nervous system?
- faster digestive function
