Which of the following glands is considered both part of the endocrine system and the nervous system?
Parathyroid gland
Thalamus
Hypothalamus
Pituitary gland
Thyroid gland
Hypothalamus
The correct answer is hypothalamus. The hypothalamus is made of nervous tissue and is a part of all vertebrate brains, placing it as part of the nervous system.

Example Question #124 : Sat Subject Test In Biology
Lipase and trypsin are secreted by what digestive organ?
Pancreas
Small intestine
Stomach
Large intestine
Salivary glands
Pancreas
Lipase and trypsin are enzymes secreted by the pancreas into the duodenum of the small intestine. These enzymes aid in the digestion of food. Salivary glands produce amylase in order to begin digestion in the mouth and the stomach aids in digestion primarily via stomach acid .
Example Question #1 : Neurotransmitters
Which of the following neurotransmitters is the primary inhibitory neurotransmitter in the human central nervous system?
GABA
Acetylcholine
Glutamate
Serotonin
Dopamine
GABA
The correct answer is GABA. GABA is the primary inhibitor used to lower the activity of cells in the human central nervous system. Glutamate, serotonin, and dopamine usually increase the activity of cells, and acetylcholine can increase or decrease cell activity depending on what cell receptor is interacting with the acetylcholine.
