Chapter 2.3 Flashcards
What are the steps to the spinal reflexive response?
Sensory Receptor-> dorsal spinal cord-> interneuron-> ventral spinal cord-> motor neuron
True/False: You are born with a spinal reflexive response.
True
True/False: When your body experiences a reflexive response, the signal does not travel to the brain.
True
What does dorsal mean?
back
What is the function of the spinal cord?
connects the brain and PNS, also allows for spinal reflexes
What is the Somatic nervous system?
A channel for incoming sensory input and outgoing commands from brain to skeletal muscles
What does the autonomic nervous system do?
regulates internal bodily environment (e.g. functioning of the heart and stomach)
What are the parts of the peripheral nervous system?
somatic nervous system and autonomic nervous system
What are the parts of the autonomic nervous system?
Sympathetic and Parasympathetic nervous system
What is the sympathetic nervous system?
Fight or flight system controls the body when it is aroused
What is the parasympathetic nervous system?
Rest and digest system controls the body during its normal rest state
What are the 3 divisions of the brain?
Forebrain, midbrain, hindbrain
Which division of the brain is considered the more sophisticated part?
forebrain
Where is the cortex located?
The outer most part of the brain located in the forebrain
What part of the brain is associated with “superhuman functions”?
cortex
What is the basal ganglia’s function?
movement
Where is the basal ganglia located?
Forebrain
What is the function of the hippocampus?
memory
What is the function of the amygdala?
emotion
What is the function of the cingulate gyrus?
emotional information processing
What is the function of the thalamus?
“relay center”; relays information from the lower brain centers into the forebrain center
What is the function of the hypothalamus?
regulates internal body states; hunger, thirst, sex drive
What is the function of the tectum?
“relay center”; relays information that comes form the spinal cord into the forebrain
What is the function of the tegmentum?
“relay center”; relays information that comes form the spinal cord into the forebrain
