LAST PART Flashcards
links the CNS to the body’s sense receptors, muscles, and glands
The Peripheral Nervous System (PNS)
is the division of the PNS that controls the external aspects of the body, including the skeletal muscles, skin, and sense organs. This system consists primarily of motor nerves responsible for sending brain signals for muscle contraction.
The Somatic Nervous System (SNS)
is the division of the PNS that governs the internal activities of the human body, including heart rate, breathing, digestion, salivation, perspiration, urination, and sexual arousal. Many of the actions of the ANS, such as heart rate and digestion, are automatic and out of our conscious control, but others, such as breathing and sexual activity, can be controlled and influenced by conscious processes
The Autonomic Nervous System (ANS)
is involved in preparing the body for behavior, particularly in
response to stress, by activating the organs and the glands in the endocrine system.
The Sympathetic Division of ANS
tends to calm the body by slowing the heart and breathing and by allowing the body to recover from the activities that the sympathetic system causes. The two systems work together to maintain vital bodily functions, resulting in
The Parasympathetic Division of ANS
the natural balance in the body’s systems
Homeostasis
the chemical regulator of the body that consists of glands that secrete hormones which influence behavior
Endocrine System
in the endocrine system is made up of groups of cells that function to secrete hormones.
Gland
is a chemical that moves throughout the body to help regulate emotions and behaviors.
Hormone
a small pea-sized gland located near the center of the brain, is responsible for controlling the body’s growth, but it also has many other influences that make it of primary importance to regulating behavior.
Pituitary Gland
an organ which secretes hormones designed to keep the body supplied with fuel to produce and maintain stores of energy; insulin regulator
Pancreas
located in the middle of the brain, which secretes melatonin, a hormone that helps regulate the wake-sleep
Pineal Gland
which are responsible for determining how quickly the body uses energy and hormones, and controlling the amount of calcium in the blood and bones
Thyroid and Parathyroid Glands
The body has 2
Andrenal Glands
Male sex glands
Testes
