Which is a limitation of electrical impulses in animals?

1they reach only cells connected by nervous tissue2they always reach every cell through blood3they can be produced continuously without reset time

Question 12

Peripheral nervous system

Difficulty: mediumSource: CBSE 2024 board familyTopic: human-brain

The peripheral nervous system consists mainly of:

1brain and spinal cord2cranial and spinal nerves3medulla and cerebellum only

Question 13

Motor neuron

Difficulty: mediumSource: CBSE 2026 board familyTopic: animal-nervous-system

A motor neuron carries an impulse:

1from a receptor to the CNS2from the CNS to an effector3across the blood to every cell

Difficulty: hardSource: CBSE 2023-2026 board familyTopic: animal-hormones

Which sequence correctly describes insulin feedback?

1blood sugar rises -> more insulin -> blood sugar falls -> insulin release reduces2blood sugar rises -> less insulin -> blood sugar rises further3blood sugar falls -> unlimited insulin release

Question 20

Nervous versus hormonal

Difficulty: mediumSource: CBSE 2023 five-mark familyTopic: animal-hormones

Which comparison is correct?

1nervous messages travel only as hormones in blood2nervous responses are usually rapid; hormonal responses are usually slower and longer-lasting3hormonal messages act only at synapses
