The correct Answer is:
To find the correct statement among the given options, we will analyze each statement one by one. ### Step-by-Step Solution: 1. **Statement A: Somatic neural system relays impulses from CNS to skeletal muscle.** - The somatic nervous system (SNS) is responsible for voluntary control of body movements via skeletal muscles. This statement is correct because it accurately describes the function of the SNS. 2. **Statement B: ANS transmits impulses from CNS to voluntary muscle.** - The autonomic nervous system (ANS) controls involuntary functions (like heart rate, digestion, etc.) and does not transmit impulses to voluntary muscles. This statement is incorrect. 3. **Statement C: Neural organization is very simple in hydra while better organized in insects.** - Hydra has a simpler nerve net organization, while insects have a more complex nervous system with ganglia. This statement is correct. 4. **Statement D: Neuron can detect, receive, and transmit stimulus both sides of the axon.** - Neurons primarily receive signals through dendrites and transmit signals through the axon. The axon does not transmit signals from both sides; it transmits signals unidirectionally. This statement is incorrect. ### Conclusion: From the analysis: - Statement A is correct. - Statement C is correct. - Statements B and D are incorrect. Thus, the correct statements are A and C. ### Final Answer: The correct statements are A and C. ---

Neural system which relays impulses from CNS to skeletal muscles is________.

The peripheral nervous system is divided into two divisions called A and B. A relays impulses from the CNS to skeletal nuscles while the B transmits impulses from the CNS to the involuntary organs and smooth muscles of the body. B is further classified into C and D neural system.

Branch of PNS which transmit impulses from CNS to involuntary organ and classified into sympathetic & parasympathetic neural system is

Part of PNS which transmit impulses from CNS to involuntary organ and classified into sympathetic & parasympathetic neural system is ____________.

Read the given statements and select the correct ones. (i)Autonomic neural system transmits impulses from the CNS to the voluntary organs and striated muscles of the body. (ii)Unmyelinated nerve fibres do not have Schwann cells which form the myelin sheath. (iii)Axonal membrane of a neuron while not conducting any impulse is comparatively more permeable to potassium ions (K^+) than to sodium ions (Na^+) (iv)A synapse is formed by the membranes of presynaptic neuron and a post synaptic neuron.

Read the following statements, Statement:-{ A:}Somatic neural system (SNS) and Autonomic nervous system (ANS) are parts of PNS. Statement:-{ B} SNS controls the actions of skeletal muscles while ANS controls the activity of involuntary organs like smooth muscles and glands of body. Choose the correct option

Read the following statements about the nervous system: I. The neural organisation in Hydra is composed of a network of neurons. II. A neuron is a macroscopic structure composed of three major parts III. Nissl's granules are present in dendrites and cell body. IV. The axons transmit nerve impulses towards the cell body. How many from the many from the above is/are correct ?

Which of the following statements are true (A) The entire process of involuntary response to a peripheral nervous stimulation is called reflex action. (B)Information regarding changes in the environment is received by the CNS through the sensory organs which are processed and analysed. (C) Reflex action occurs without conscious effort (D) Reflex action requires the involvement of a part of the CNS (E) Signals from sensory organs goes to spinal cord via ventral root. Choose the correct options from given below:-

Reflex actions are very rapid, involuntary, stereotyped behaviours in which some kind of stimuli evoke a fast, short lived response. Select the correct option w.r.t. reflex actions Statement A : In a Knee-jerk reflex, more than one synapse is formed in the reflex path. Statement B : The afferent neurons in a reflex action transmit the impulses received from sensory organs via dorsal nerve root into CNS
