Question 24

Pituitary Gland

Answer 24

Base of the brain near Pons and Hypothalamus
Releases a variety of hormones throughout the body, stimulating actions in other endocrine glands

Question 25

Thyroid

Answer 25

in the front of neck and
Produces hormones that regulate energy, metabolism and growth

Question 26

Parathyroid(s)

Answer 26

Front of neck above Thyroid

Pineal Body

Answer 30

it’s beneath Corpus Callosum, located in the Midbrain and produces melatonin-regulates sleep and wake cycles

Question 31

Suprachiasmatic Nucleus

Answer 31

A pair of grain-of-rice-sized, 20,000-cell clusters in the hypothalamus that receive light input from the retina via the optic nerve and regulate the body’s circadian rhythms (sleep cycle)

Question 32

How is rewiring an element of plasticity?

Answer 32

Rewiring is a plasticity mechanism that alters connectivity between neurons.
