The ________ is the fundamental element of the nervous system.
Answer: A. Neuron
The neuron is the basic building block/fundamental unit of the entire nervous system.
There are ________ pairs of spinal nerves in total.
Answer: D. 31
Humans have 31 pairs of spinal nerves branching off the spinal cord.
Branch like extensions from the end of a neuron that carry messages to other cells through the neuron is:
Answer: B. Dendrites
Dendrites are the branch-like extensions that receive/carry messages from other neurons into the cell.
Which of the following is the Master Gland?
Answer: B. Pituitary gland
The pituitary gland is called the 'master gland' because it controls the secretions of most other endocrine glands.
Myelin Sheath protects ________ in the neuron.
Answer: A. Axon
The myelin sheath is a fatty insulating layer wrapped around the axon that protects it and speeds up nerve impulse conduction.
If Ali is in emergency situation then which part of nervous system would be activated?
Answer: B. Sympathetic
The sympathetic nervous system triggers the 'fight-or-flight' response in emergencies, increasing heart rate and alertness.
What is Neuron? Write its various types.
A neuron is the basic structural and functional unit of the nervous system — a specialized cell that receives, processes and transmits information through electrical and chemical (neurotransmitter) signals. It has a cell body (soma) with a nucleus, dendrites that receive signals, and an axon that transmits the signal to other cells.
Types of neurons: (1) Sensory (afferent) neurons — carry information from sense organs to the central nervous system; (2) Motor (efferent) neurons — carry commands from the CNS to muscles and glands; and (3) Interneurons (association neurons) — found within the brain and spinal cord, connecting sensory and motor neurons and processing information between them.
What is meant by autonomic nervous system?
The autonomic nervous system (ANS) is the part of the peripheral nervous system that controls involuntary bodily functions — such as heart rate, digestion, breathing rate, and glandular secretion — without conscious effort. It has two branches that work in balance: the sympathetic nervous system, which activates the body's 'fight-or-flight' response during stress or emergencies (increasing heart rate, releasing adrenaline), and the parasympathetic nervous system, which promotes the 'rest-and-digest' state, calming the body down and conserving energy once the emergency has passed.
