Formative Assessment

The Endocrine system uses chemical signals called

• target cells

• hormones

• glands

• neurons

Hormones are released into the blood stream by

• target cells

• endocrine glands

• protein receptors

• enzymes

Which of the following acts as a part of both the nervous and the endocrine system

• The hypothalamus

• The thymus

• The pancreas

• The myelin sheath

What is not true about the endocrine glands

• secrets hormones

• release chemicals into the blood stream

• release chemical into ducts

• richly vascularized

Exocrine glands are

• ductless glands

• highly vascularized

• Secret the chemicals it produces through special ducts

• release hormones directly in the blood

Islets of Langerhans are

• exocrine tissues the release pancreatic juices

• endocrine tissues the secret insulin

• exocrine tissues that secret insulin

• endocrine tissues the secret insulin and glucagon

Upon receiving a stimulus, an endocrine gland or endocrine tissue is induced to release a specific hormone into the bloodstream; hormone molecules are carried by the blood to target organs where they bind to specific _____________

• organ

• tissue

• receptor

• chemical

Low blood glucose level stimulates the secretion of

• insulin

• GnRH

• growth hormone

• glucagon

High blood glucose level triggers the pancreas to secret

• insulin

• GnRH

• glucagon

• Thyroxin

Glucose is stored in liver in the form of

• glycogen

• glucagon

• amino acids

• fatty acids
