Term
Forebrain functions
Definition
recieves and integrates information from nose, eyes, and ears, high concetration of integrating centers.
Term
Midbrain functions
Definition
coordinates reflex responses to sight and sounnds.
Term
Hindbrain functions
Definition
reflex control of bodily functions, motor and mental dexterity.
Term
Vertebral Trend of invertebrate brain
Definition
olefactory lobe develops in forebrain, brain becomes thickened with interneurons.

Storage and retreival of information, learning from past experiences.
Term
Two major categories of the PNS
Definition
somatic and autonomic nervous system
Term
somatic
Definition
Motor responses
Term
Autonomic
Definition
involuntary responses
Term
Two types of autonomic nerves
Definition
sypathetic and parasympathetic
Term
Sympathetic nerves
Definition
speed up body processes
Term
Parasympathetic
Definition
slow down bodily functions
Term
parts of the forebrain
Definition
cerebrum, olefactory lobes, thalamus, and hypothalamus
Term
parts of the midbrain
Definition
tectum
Term
Parts of the hindbrain
Definition
medulla oblongata, cerebellum, pons
Term
cerebrum
Definition
deals with olefactory input and motor responses
Term
olefactory lobes
Definition
evolved once we became reliant on chemical cues (odors)
Term
Thalamus
Definition
coordinating center and relay station for sensory input
Term
Hypothalamus
Definition
center for homeostatic control of internal environment, central to internal organ activities
Term
Tectum
Definition
in mammals reflex center that relays sensory signals to higher integrating centers.
Term
Medulla Oblongata
Definition
contains reflex centers for repiration and blood circulation.
Term
cerebellum
Definition
integrates signals from sensory organs with motor signals from forebrain, language and mental dexterity.
Term
Pons
Definition
traffic center for signals traveling from cerebellum to forebrain.
Term
frontal lobe
Definition
planning of movements, aspects of memory, inhabition of unsuitable behavior.
Term
Occipital lobe
Definition
vision
Term
temporal lobe
Definition
hearing, advances visual processing
Term
Parietal lobe
Definition
visceral sensation
