Neural control and Coordination Flashcards
As you know, the functions of the organs/organ systems in our body must be coordinated to maintain _________.
Homeostasis
The process through which two or more organs interact and complement the function of one another is called
Coordination
Endocrine system provides chemical integration by the chemicals called ______.
Hormones
The neural system of all animals is composed of highly specialised cells called
Neurons
The neural system of all animals is composed of highly specialised cells called neurons which can detect, receive and transmit different kinds of _______
Stimuli
A structure containing a number of nerve cell bodies, typically linked by synapses, and often forming a swelling on a nerve fibre.
Ganglia
The _____________________ includes the brain and spinal cords and is the site of information processing & control
Central Neural System (CNS)
All the nerves of the body associated with Central Nervous System (CNS) come under which neural system
Peripheral Neural System (PNS)
The nerve fibres that transmit impulses from tissue/organs to CNS are called
Afferent nerve fibres
The nerve fibres that transmit regulatory impulses from the CNS to the concerned peripheral tissue organs are called
Efferent fibres
The neural system which relays impulses forms CNS to skeletal muscles is called?
Somatic neural system
The neural system which relays impulses forms CNS to skeletal muscles is called?
Somatic neural system
The neural system which transmit impulses from the CNS to involuntary organs and smooth muscles of the body is called
Autonomic neural system
Organs like heart, blood vessels, lungs, stomach, glands and intestines which are controlled by the the autonomic nervous system are called
Involuntary organs
The autonomic nervous system is classified into two separate sub-systems, one is parasympathetic neural system and the other is
Sympathetic neural system
______________ is part of PNS that comprises the whole complex of nerves, fibres, ganglia and plexuses by which impulses travel from the CNS to the viscera and from the viscera to the CNS.
Visceral nervous system
A neuron is composed of three major parts. The part which contains cytoplasm with typical cell organelles and Nissl’s granules is called
Cell body
Short fibres which branch repeatedly and project out of the cell body also contain Nissl’s granules are called
Dendrites
______________ is a long fibre, the distal end of which is branched.
Axon
Granular bodies found in cytoplasm within the cell body of a neuron are called
Nissl’s granules
Each branch of an axon terminate in a bulb like structure called___________
Synaptic knob
Synaptic vesicles containing chemicals and found inside the synaptic knob are called
Neurotransmitters
A nerve impulse is transmitted from one neuron to another through junctions called ________
synapse
The axons transmit nerve impulses away from the cell body to a synapse or to a ______________
Neuro-muscular junction
