Brain Structure
The largest part of the brain
Cerebrum
Part of the diencephalon that regulates our sleep cycles and emotions
Hypothalamus
The 2 structures that protect the spinal cord
Meninges and vertebral column of the spine
# of the pairs of cranial nerves and the # of peripheral nerves in the body
12, 31
Major organs of the CNS
Brain and spinal cord
The 4 lobes of the brain
Frontal, parietal, occipital, temporal
Lobe responsible for logic (planning, reasoning, communication) (parietal, frontal, temporal, occipital)
Frontal lobe
Common example of a reflex ark
Patellar tendon reflex
Cranial nerve responsible for smelling
Olfactory nerve (CN 1)
3 layers of meninges from superficial to deep
Dura mater - arachnoid space - pia mater
Forms most of the diencephalon
Thalamus
Part of the brainstem that controls autonomic functions like blood pressure, swallowing, sneezing, or coughing
Medulla oblongata
The patellar reflex is this type of reflex (somatic or autonomic)
Somatic
Branch of the PNS that is involuntary (autonomic vs somatic)
Autonomic
Fluid produced that protects the CNS
Cerebrospinal fluid
Thalamus, hypothalamus, pineal gland
Temporal lobe
This neuron carries information to the brain
Afferent
This type of nerve signal carries information to the brain and spinal cord (sensory, motor, autonomic)
Sensory
Connects the 2 hemispheres together
Corpus callosum
Major part of the brain that is responsible for muscle memory and maintaining posture and balance
Cerebellum
The spinal cord is connected to this part in the brain
Medulla oblongata
3 main jobs of the PNS
1. Senses
2. Movement
3. Unconscious processes
