Which of the following is associated with the prefrontal cortex?
Walking
Fine motor skills
Self-regulation
Recognizing faces
Long-term memory
The Correct Answer is C
A. Walking: Walking depends mainly on motor cortex, brainstem pattern generators, cerebellum, and spinal circuits rather than prefrontal cortex.
B. Fine motor skills: Fine motor control relies on motor and premotor cortices and cerebellar coordination; prefrontal cortex helps plan but isn’t the primary motor executor.
C. Self-regulation: The prefrontal cortex is centrally involved in executive functions such as impulse control, planning, and self-regulation.
D. Recognizing faces: Face recognition relies primarily on temporal-lobe regions (e.g., fusiform gyrus), not the prefrontal cortex.
E. Long-term memory: Long-term declarative memory depends on medial temporal structures (hippocampus) and distributed networks, not primarily the prefrontal cortex.

B. Boys' friendships involve more competition than girls' friendships do:boys’ friendships tend to be more activity- and competition-based, whereas girls’ friendships emphasize intimate talk and emotional support.
C. Androgynous boys are less likely than masculine boys are to form intimate ties because they are concerned about appearing too feminine:Incorrect: androgynous boys (who display both instrumental and expressive traits) are often more capable of forming intimate ties than strictly masculine-stereotyped boys.

B. Phenylketonuria (PKU):PKU is an inherited inability to metabolize the amino acid phenylalanine, causing accumulation that can lead to brain damage and intellectual disability if untreated.
C. Huntington's disease:Huntington’s is a genetic neurodegenerative disorder caused by a trinucleotide repeat expansion, not an amino-acid metabolic defect in infancy.
D. Jaundice: Jaundice involves elevated bilirubin in newborns and can cause kernicterus if severe, but it’s not an amino-acid metabolic disorder like PKU.
E. Meningitis: Meningitis is inflammation of the meninges from infection and is not caused by metabolic inability to process an amino acid.
