CN II-XII
How many pairs of cranial nerves are there?
12 pairs
What does EEG stand for :3
Electroencephalogram :3
This largest part of the brain is responsible for thinking, memory, and voluntary movement.
Cerebrum
What three main components does the diencephalon include?
Thalamus, hypothalamus, and epithalamus
What are the folds and grooves on the brain called?
Gyri and Sulci
The cranial nerves are a part of the _____ nervous system
peripheral
This type of brain wave is associated with relaxed wakefulness, such as when your eyes are closed but you're not asleep :3
What are alpha waves? :3
This brain region maintains balance and coordinates fine muscle movement
Cerebellum
What is the function of the thalamus and where does it relay information?
Filters sensory information while relaying a small portion to the cerebral cortex and most to the basal nuclei.
What structure separates the two cerebral hemispheres?
Longitudinal fissure
The cranial nerves connect to the spinal cord
false, connect to the brain
EEGs are often used clinically to help diagnose this neurological disorder characterized by abnormal electrical activity and seizures I wish I had a better anatomy teacher
What is epilepsy :3
This part of the brainstem controls vital functions like heart rate, breathing, and blood pressure.
medulla oblongata
What part of CNS coordinates voluntary and autonomic functions and what are examples of autonomic functions?
The Hypothalamus and examples of autonomic functions include heart rate, digestion,
respiration rate, salivation, perspiration.
What is the function of the primary motor cortex?
Controls voluntary movement
How many of the 5 senses are the cranial nerves responsible for?
all 5
This type of brain wave is commonly seen in light sleep or drowsiness and is faster than delta waves :3
What are theta waves? :3
This structure acts as the main sensory relay station, sending information to the cerebral cortex
Thalamus
What are two key components of the epithalamus?
The choroid plexus and pineal body
What does the primary sensory cortex do?
Processes touch, pain, temperature, and pressure
Name 5 functions of the cranial nerves
play a part in: sight, smell, balance, hearing, taste, swallowing, eye movement, face movement, jaw movement, scalp movement, tongue movement
A sudden spike in abnormal electrical activity on an EEG could indicate this type of event in the brain :3
What is a seizure? :3
This division of the brain includes the thalamus, hypothalamus, and epithalamus and is responsible for homeostasis and sensory integration
Diencephalon
List all the functions of the hypothalamus
Produce emotions and behavioral drives, coordinate nervous and endocrine
systems, secrete hormones, coordinate voluntary and autonomic functions , regulate body temperature
What is the role of association areas in the cerebral cortex?
Interpret sensory input and coordinate complex thinking and movement
