UPDATE
Define the function of the Endocrine System
The Endocrine System controls the secretion of hormones from glands located
throughout the body.
Define a Gland
A gland is an organ that secretes hormones into the bloodstream.
Define Hormone
A hormone is a chemical substance that is released in small amounts and travels
through the bloodstream to other tissues and organs to transfer information or
instructions.
Why is the Pituitary Gland known as the Master Gland?
The pituitary gland regulates the other glands of the body.
What are the sections of the Pituitary Gland?
Anterior lobe, intermediate lobe, posterior lobe; Anterior lobe is the adenohypophysis;
Posterior lobe is the neurohypophysis.
What are the roles of the hormones secreted by the thyroid gland?
To maintain the basic metabolic rate of the body, the growth of the body, and the
metabolism of nutrients, water, vitamins, and minerals.
,The three groups of hormones secreted by the adrenal cortex are known as the A)
_____ B) ______ C) ______
A) Glucocorticoids B) Mineralocorticoids C) Androgens
Where is the Thymus Gland located, and what is the function of the hormones
secreted by this gland?
The Thymus Gland is located in the mediastinum and the hormones secreted by this
function in the immune system.
What is the function of the nervous system? What are the main divisions of the
nervous system?
The nervous system coordinates all of the activities of the body through receiving
information, interpreting that information, and then sending responses to the body to
maintain homeostasis. The main divisions of the nervous system are the central
nervous system and the peripheral nervous system.
What are the names of the meninges that cover the brain and the four main
structures of the brain?
The three meninges are the dura mater, the Pia mater, and the arachnoid mater. The
four major structures of the brain are the cerebellum, the cerebrum, the brain stem, and
the diencephalon.
What are the three functions of the spinal cord?
1) conduct sensory impulses from the peripheral nervous system to the brain, 2)
conduct motor impulses from the brain to the peripheral nervous system, 3) process the
body's reflexes.
Where do cranial nerves originate, and what are their functions?
, Cranial nerves originate in the brain. Their functions are to innervate the senses, the
motor movements of the head and shoulders, swallowing, breathing, speech, and the
muscles of the thoracic and abdominal cavities.
Where do spinal nerves originate, and what are their functions?
Spinal nerves originate in the spinal cord, and they have sensory and motor functions
throughout the body.
What are the two branches of the autonomic nervous system? What are their
functions?
The sympathetic and the parasympathetic divisions. These two divisions have opposite
effects on the body. The parasympathetic branch regulates the daily functioning of the
body and maintains homeostasis. The sympathetic branch is activated in emergency
situations and creates the "fight-or-flight" response to stress.
What is the function of the ear?
The function of the ear is to detect sound waves and transmit that sound to the brain. It
also facilitates balance, positioning, and equilibrium in the body.
What are the divisions of the ear? What are the main components of each
section?
The divisions of the ear are the outer ear, the middle ear, and the inner ear. The outer
ear consists of the auricle and the external acoustic meatus, ending at the tympanic
membrane. The middle ear consists of the ossicles, ending at the oval window. The
inner ear consists of the cochlea, vestibule, and semicircular canals and ends at the
cochlear nerve.
What are the divisions of the eye?
