Basic Brain Anatomy
The part of the brain that is in charge of most of our basic functions.
Hint: it connects to the spinal cord
THE BRAIN STEM
The lobe of the brain used for sight processing
The Occipital lobe!
What neurotransmitter is used at all somatic motor synapses?
Acetylcholine
The human brain contains approximately ______ neurons.
86 billion neurons
Each neuron forms connections to other neurons, which could add up to 1 quadrillion (1,000 trillion) connections
The system of the brain that is in charge of most of our emotion processing and some of our hormonal release.
The Limbic System
The memory center of the brain
Hint: an herbivore water creature
The Hippocampus
What neurotransmitter is used to slow down the heart rate?
Acetylcholine
You actually only use about 10% of your brain at any given moment. True or false?
False
The "little brain." it is in charge of more basic functions like balance, and muscle movement coordination.
The Cerebellum
This a bridge of nerves between the two hemispheres of the brain
The corpus collosum!
The primary ____________ cortex is located in the parietal lobe in the postcentral gyrus and helps process sensory information, such as tactile information, pain, temperature, and where you are in space.
Primary somatosensory cortex
An adult brain weighs about _____ pounds
3
This brain structure is divided into four lobes: frontal, temporal, parietal, occipital
The decision making and higher processing lobe of the brain
The frontal lobe!
All sensory information is sent first to the thalamus except the sense of:
Smell
About ___% of the brain is made up of water
75%
This hemisphere is associated with musical traits, creativity, and spatial reasoning
The right hemisphere!
A little structure in the brain where lots of emotions are processed and given meaning. Sometimes called the "fear center" of the brain.
The Amygdala
Which brain structure is responsible for producing a hormone that triggers thirst mechanisms?
Hypothalamus
The brain has no pain receptors. true or false?
True. There are no pain receptors in the brain itself. But the meninges (coverings around the brain), periosteum (coverings on the bones), and the scalp all have pain receptors
