2. What is the Endocrine system?
-The Endocrine system is comprised of various
glands that secrete hormones into the blood
stream which in turn affect tissues cells with
receptors for the specific hormone.
-This process helps regulate, growth, response
to stress, water and mineral balance, and
metabolism.
3. What are the structures of the
Endocrine system?
• The Endocrine system is comprised of:
– Pineal gland(body)
– Hypothalamus
– Thyroid
– Parathyroid
– Pituitary gland
– Adrenal glands
– Pancreas
– Testes
– Ovaries
15. Central Nervous System(CNS)
• Comprised of the Brain and Spinal Cord
• The functional unit of the CNS is the Neuron
• Neurons release neurotransmitters from the Axon
to receiving Dendrites at the synaptic gap.
• The Brain is essential in awareness, movements,
sensations, thoughts, speech, and memory
awareness, movements, sensations, thoughts,
speech, and memory (some reflexes occur via the
spinal cord pathways without brain involvement)
17. • The Hypothalamus connects these two systems
via the Pituitary gland by secreting
Neurohormones that stimulate or inhibit the
release of Pituitary hormones
• Pituitary hormones stimulate the release of other
hormones from other endocrine structures
• Reproductive hormones affect the development
of the nervous system.
• Hormones provide feedback to the brain to affect
neural processing.
