Brain Anatomy
The outer part of the cerebral cortex is made of _____ matter and the inner part is made of _______ matter
grey, white
What is the function of the prefrontal cortex
These type of fibers carry efferent signals out of the brain and down the spinal cord.
The central sulcus is the border between these two cortices
What are the primary motor and primary somatosensory cortex
Located in the middle of our brain, this is known as the afferent "relay station" of the brain. Most afferent neurons will synapse here before going to their respective cortices.
What is the Thalamus
When we our visual receptors receive a stimulus, it goes to the ______ cortex in the _____ lobe.
Origin: Choroid plexus
1. Lateral ventricles
2. 3rd ventricle
3. 4th ventricle
4. Cerebral aqueduct
You just finished taking a test and you are thinking about quietly getting up and leaving the class so not to disturb anyone. You are likely using this area of the brain.
What is the premotor cortex
A child has just woken up screaming from a very bad nightmare. He cannot remember the dream that well, but it still managed to foster extreme emotional response. This brain structure was the primary driver for his dream.
What is the amygdala
What is decussation
A person has sustained a traumatic brain injury, and is unable to smoothly perform motor skills. Sometimes their limbs will involuntarily jerk. Damage has likely been incurred to this brain structure.
What are the basal nuclei
A patient reports a variety of hormone deficiencies after a car crash that caused a traumatic brain injury. Hormones like thyroid hormone, growth hormone, oxytocin, etc. are all deficient in this patient to the point where they are unable to perform necessary homeostatic functions without outside injections. Based on your knowledge of the brain, you know this structure has likely incurred damage.
What is the hypothalamus
