Neural Control and Coordination

Control and co-ordination of head movements in response to visual and auditory stimuli is carried out by
1 Corpora striata
2 Corpora cavernosa
3 Crura cerebri
4 Corpora quadrigemina
Explanation:
D The corpora quadrigemina are four rounded structures in the midbrain. They consists of the superior colliculi, involved in visual functions and eye movements, and the inferior collicule, responsible for auditory processing. These structures help process visual and auditory information and coordinate appropriate responses.

When stimulus is applied to a membrane of neuron, it causes rapid influx of?
1 \(\mathrm{K}^{+}\)
2 \(\mathrm{Mg}^{++}\)
3 \(\mathrm{Ca}^{++}\)
4 \(\mathrm{Na}^{+}\)
Explanation:
D When a stimulus is applied to a neuron's membrane, it causes a rapid influx of \(\mathrm{Na}^{+}\)ions. This influx of sodium ions leads to depolarization, which is an essential step in generating an action potential and transmitting nerve impulses along the neuron.

Neurogenic heart receives stimulus for contraction from fibres.
1 Elastin
2 Collagen
3 Nerve
4 Muscle
Explanation:
C In the neurogenic heart, the nerve from the brain initiates cardiac movement. Neurogenic heart is found in lower invertebrates like annelids and arthropods that receives stimulus for contraction from nerve fibres.

The velocity of conduction of nerve impulse in frog is
1 \(300 \mathrm{~m} / \mathrm{s}\)
2 same as of electricity
3 faster than sound
4 \(30 \mathrm{~m} / \mathrm{s}\)
Explanation:
D The velocity of conduction of a nerve impulse in a frog is \(30 \mathrm{~m} / \mathrm{s}\). This relatively slow speed is due to the fact that nerve impulses in frogs and many other animals are conducted through unmyelinated nerve fibres.
