What is the function of each organ in the nervous system?
Nerves and Sensory Organs Make Up the Peripheral Nervous System. Together, the central nervous system (CNS) and the peripheral nervous systems (PNS) transmit and process sensory information and coordinate bodily functions. The brain and spinal cord (the CNS) function as the control center.
Are nerves organs?
Like other systems in the body, the nervous system is composed of organs, principally the brain, spinal cord, nerves, and ganglia. These, in turn, consist of various tissues, including nerve, blood, and connective tissue. Together these carry out the complex activities of the nervous system.
What are the main organs involved in the endocrine system?
While many parts of the body make hormones, the major glands that make up the endocrine system are the:
- hypothalamus.
- pituitary.
- thyroid.
- parathyroids.
- adrenals.
- pineal body.
- the ovaries.
- the testes.
What is the major organ of endocrine system?
The major glands of the endocrine system are the hypothalamus, pituitary, thyroid, parathyroids, adrenals, pineal body, and the reproductive organs (ovaries and testes). The pancreas is also a part of this system; it has a role in hormone production as well as in digestion.
What are the major structures of the nervous system?
The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. The major structures of the nervous system include the brain, spinal cord, and nerves.
What are the three general functions of the nervous system?
Overview of the entire nervous system. The nervous system has three main functions: sensory input, integration of data and motor output. Sensory input is when the body gathers information or data, by way of neurons, glia and synapses.
What are the parts of the autonomic nervous system?
Autonomic Nervous System Anatomy. Your autonomic nervous system lies almost entirely outside of the central nervous system and involves two main parts: the craniosacral part (parasympathetic), and the thoracolumbar part (sympathetic). These are sometimes thought of as being opposite to each other, ultimately striking a balance within the body.
What is the hierarchy of the nervous system?
Hierarchical organisation in the nervous system. Functionally, the nervous system is organised hierarchically; this is analogous to a business corporation with workers and managers. The hierarchy consists of effectors (sensory and motor) and different levels of information processing and integration in the spinal cord, brainstem and forebrain.
