What is in the hindbrain?
medulla, reticular formation, locus coeruleus, cerebellum
-
Medulla
involuntary reactions
-
Reticular formation
cells that thread into the midbrain, alters activities for brain
-
Locus coeruleus
necleus in reticular formation, focus and attention
-
Cerebellum
memory, movement, impulse
-
What is in the midbrain?
substania nigra, striatum
-
Substanuia nigra and striatum
work together for smooth movement
-
What is in the forebrain?
thalamus, hypothalamus, suprachiasmatic nuclei, cerebrum
-
Thalamus
senses, make sense out of info
-
Hypothalamus
hunger, thrist, sex drive
-
Suprachiasmatic nuclei
in the hypothalamus, biological rhythym
-
Cerebrum
- amygdala- takes in more than 1 sensory info at a time
- hippocampus- memory (remember the hippo)
-
What is in the cerebral cortex?
sensory cortex, motor cortex, association cortex
-
Sensory cortex
takes in senses
-
Motor cortex
in the frontal lobe, voluntary movement
-
Association cortex
receiving info from more than 1 sense
-
Sympathetic
fight or flight, molbolizes
-
Parasympathetic
energy conserving
-
Pinna
outside of the ear, collects sound
-
Ear canal
transports sound waves to inner ear
-
Tympanic member (ear drum)
match sound wave with a vibration
-
Malleus (hammer)
amplify sound (works together with incus and stapes)
-
Incus (anvil)
amplify sound (works together with malleus and stapes)
-
Stapes (stirrup)
amplify sound (works together with malleus and incus)
-
Semi-circular canals
further amplifies sound, sense of balance
-
Aditory nerve
info gets to brain to turn into sound that we hear
-
Cochlea
fluid filled with tiny hairs at its base, transduces vibrations to neural messages
-
Dendrites
recieve info and takes it to the cell
-
Axon
an extension from the nerve cell that carries info away from cell
-
Synapse
space between 2 neurons, communicate through chemical reactions
-
Neurotransmitter
chemical in the brain that makes a neuron carry out a specific function
