Injury vagus nerve in humans is not likely to affect: (C.B.S.E 2004)
The vagus nerve primarily affects the heart, gastrointestinal tract, and other organs. However, it does not control the movement of the tongue; that is primarily the function of the hypoglossal nerve.
Which of the following is not strictly considered a part of neuron? (C.P.M.T 1998)
The myelin sheath is not strictly considered a part of the neuron itself. It is produced by glial cells (Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system) and functions to insulate the axon and speed up the transmission of nerve impulses.
Centers for sense of smell are located (M.P.P.M.T 1999)
The centers for the sense of smell, also known as olfaction, are located in the olfactory lobes. The olfactory lobes are part of the brain responsible for the detection and processing of odor molecules. This region is specifically dedicated to the sense of smell.
Nerve related to diaphragm is (M.P.P.M.T 1999)
The nerve related to the diaphragm is the phrenic nerve. The phrenic nerve originates in the neck (C3-C5) and passes down between the lung and heart to reach the diaphragm. It is crucial for breathing because it controls the contraction of the diaphragm.
Node of Ranvier is the place where (C.B.S.E.P.M.T 2002)
The Node of Ranvier is a gap in the myelin sheath of a nerve, where the myelin sheath is discontinuous. These nodes are critical for the rapid conduction of nerve impulses along the axon, as they allow for saltatory conduction, where the action potential jumps from one node to the next.
How many pairs of spinal nerve are found in human? (Guj C.E.T 2006)
Four healthy people in their twenties got involved in injuries resulting in damage and death of a few cells of the following . Which of the cells are least likely to be replaced by new cells ? (C.B.S.E 2005)
Neurons are least likely to be replaced by new cells. Unlike liver cells, osteocytes, and cells of the Malpighian layer of the skin, neurons do not regenerate easily. Damage to neurons in the central nervous system (CNS) is often irreversible because mature neurons do not undergo cell division.
One of the examples of the action of the autonomous nervous system is : (C.B.S.E 2005)
Peristalsis of the intestines is an example of the action of the autonomic nervous system. The autonomic nervous system controls involuntary actions in the body, including the movement of food through the intestines (peristalsis). The knee-jerk response and swallowing of food are primarily under somatic nervous control, while the pupillary reflex is autonomic but it is less directly related to the context of peristalsis as a clear example.
Which of the following cranial nerve is not a motor nerve.
The second cranial nerve (II), also known as the optic nerve, is responsible for vision and is not a motor nerve. Motor nerves primarily control muscle movements, whereas the optic nerve transmits visual information from the retina to the brain.
Which animals have developed capacity of regeneration ?
