CHEMICAL SIGNALS MAINTAIN HOMEOSTASIS Endocrine System: a system of glands that secrete hormones to regulate body function Hormones: chemical messengers or regulators • they are released by cells in one part of the body and affect cells in other parts of the body to speed up or slow down processes. Endocrine Hormones – are produced in glands and secreted directly into the blood and distributed by the circulatory system. Makes hormones and regulates the pituitary gland Pineal gland (makes serotonin

The divisions of the nervous system are the Central Nervous System (CNS) and the Peripheral Nervous System (PNS). The CNS is made of two parts the brain and the spinal cord. The PNS is made up the Somatic nervous system and the automatic system. The somatic nervous contains the peripheral nerve fibers that deliver sensory information to the CNS and motor nerve fibers that go to the skeletal muscle. The central nervous system sends messages from the brain to the rest of the body. (Divisions of The

Assignment 3 Written Essay Questions 1. a) We are able to experience different types of sensations because our nervous system encodes messages. German physiologist Johannes Muller in his doctrine of specific nerve energies described a kind of code which is anatomical. In his doctrine‚ Muller explains that different sensory modalities exist because signals received by the sense organs stimulate different nerve pathways that lead to different areas of the brain. For example‚ when the ear

neurotransmitter with their receptors cause’s vasoconstriction and beta adrenergic receptors increases the heart rate and show vasodilation. (Davidyan‚ 2017) The parasympathetic nervous system decreases the blood pressure as well as heart rate through vagus nerve. The diameter of the blood vessels is regulated by the vasomotor system. Vasomotor nerves made up of sympathetic motor nerves transmit impulses to the vasomotor center to innervate smooth muscles in arteries which maintain a vasomotor tone to bring

Visceral motor is directed from hypothalamus and midbrain and is involuntary‚ but has input from cortex and thalamus. Somatic lower motor neuron is in ventral horn of gray matter and neurotransmitter at skeletal muscle is Ach. Visceral motor comes from

The nervous system is one of the smallest yet one of the‚ if not the most‚ complex systems in the human body. It can be broken down into two main subdivisions‚ the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system contains about 85 billion neurons and includes the spinal cord and brain. It is considered the control center of the body and processes all types of incoming sensory information. The peripheral nervous system is composed of all the other tissue
