This stage of prenatal development is often said to be the most critical due to the rapid differential growth of the fetus during this period.
What is the embryonic stage?

The blood supply to the cuneate fasciculus comes from this artery.
What is the posterior spinal artery?

The pineal gland is found within the epithalamus of the diencephalon and works to elicit this function.
What is secrete melatonin to decrease arousal? (makes you sleepy)

This association area is often involved in social behavior and decision making. It is also a major player in the regulation of mood, recognition of disapproval, and activation of the autonomic nervous system, eliciting embarrassment.
What is ventral prefrontal association area?

The olfactory nerve (CN I) is a sensory nerve that functions to provide smell. It originates from this structure.
What is the cribriform plate of the ethmoid bone?

The blood supply to the diencephalon comes primarily from the circle of Willis. List one of the four arteries that contribute to this arterial circle.
What is Anterior cerebral artery?
What is Posterior cerebral artery?
What is Anterior communicating artery?
What is Posterior communicating artery?

The occipital lobe and primary visual cortex are supplied by this artery.
What is posterior cerebral artery?
300
Axons for this cranial nerve cross the midline and exit the brainstem posteriorly to innervate the body of this muscle.
What is the superior oblique muscle?
300
Spina bifida is a developmental disorder that occurs due to the failure of this structure to close.
What is the inferior (caudal) neuropore?

While the primary auditory cortex processes the volume and pitch of a particular sound, the secondary association area for sound elicits this fuction.
What is classifies/analyzes sound and compares it with memories?

The glossopharyngeal nerve (CN IX) is a mixed cranial nerve that yields sensory and motor function. It provides motor innervation to this muscle and the special sense of taste to this portion of the tongue. (2 answers)
What is stylopharygeus muscle?
What is posterior 1/3 of the tongue?
400
This stage of brain development is characterized by migrating neurons that are transforming into specific nuclei or ganglia with specialized functions.
What is cell differentiation stage?
500
A patient is sent to your office after experiencing a hemisection of the right side of their spinal cord. Their deficits include contralateral loss of pain and temperature and ipsilateral loss of discriminative touch to the lower extremity. These systems are affected.
What is anterolateral system (ALS) and posterior column medial lemniscus system (PCML)?
500
A 39-year-old male is brought to the emergency department by his wife who has concerns about some of his recent behaviors. Although he knows how to put on his shoes, he has recently been performing this task out of order (shoes>socks>tie laces). The doctor confirms this behavior is indicative of a motor planning issue. This nucleus of the dorsal thalamus is likely involved.
What is ventral anterior nucleus of the dorsal thalamus?
500
You are treating a patient who has undergone a severe stroke, damaging the connection between the two primary language centers on the dominant side of her brain. She can comprehend what you say and converse with you, but cannot create a meaningful reply. She likely has this condition.

A patient from your clinic has been rushed to the emergency department after suddenly experiencing trouble swallowing (Dysphagia), irregular tachycardic pulse, and shortness of breath, resulting in fast, shallow respirations. You suspect this nerve has been damaged.
What is Vagus nerve (CN X)?

A 12-year-old individual complains of weakness in his lower extremities and has recently been unable to control his bowel and bladder. He visits his primary care physician, who orders an ultrasound that reveals a fatty tumor in his lower back. You expect this may be the cause of his symptoms.
