Chapter 2c Nervous & Endocrine Systems Flashcards
What is the Nervous System?
The full set of nerves that connect your brain with all the other parts of your body. The nervous system is what enables your brain to act as a command center, sending and receiving messages from all over your body.
What is the Central nervous system:
The brain and the spinal cord. All communication with the brain must move through the central nervous system
What is the Peripheral nervous system:
The neurons that connect the central nervous system to other parts of the body.
What is the Somatic nervous system
The part of the peripheral nervous system that connects the central nervous system to the parts of the body you control voluntarily
What is the Autonomic nervous system
The part of the peripheral nervous system that connects the central nervous system to the parts of your body you control involuntarily.
What is the Sympathetic division
What is the Parasympathetic division
Sympathetic division is the part of your autonomic nervous system that revs your body up in response to stressors.
The parasympathetic division is the part of your autonomic nervous system that calms your body down when stressors decrease
What is the Endocrine System?
The set of glands that send hormones throughout the body via the bloodstream.
What are Hormones?
Chemicals made by the glands of the endocrine system, affect certain tissues throughout the body. Hormones influence virtually every important function within your body, including your appetite, mood, energy level, sleep schedule, sex drive, metabolism, digestion, and more.
What is the Pituitary gland
The “master gland” in the brain, which produces human growth hormone and also controls all of the other glands in the body. Although it is no bigger than the eraser on the end of a pencil, your pituitary gland is in charge, either directly or via control of other glands, of some remarkably important stuff: how tall you grow, your metabolism rate, the ratio of muscle to fat in your body, when puberty kicks in, your blood pressure, your body temperature, the production of breast milk after childbirth, and much more.
What are the Adrenal glands
Glands located on top of the kidneys that produce hormones to arouse the body in response to stress. One of those hormones, named after the gland itself, you know well: adrenaline.
What is the Pineal Gland?
Produces Melatonin, a hormone related to serotonin that influences sleep and wake cycles
What is the Thyroid gland?
Produces hormones that influence metabolism, body temperature, and blood pressure
