Comprehensive Overview of the Nervous System

1. What is the major function of the nervous system?

The nervous system is responsible for producing hormones

The nervous system primarily regulates body temperature

The nervous system functions to help with digestion

The correct answer describes the major functions of the nervous system accurately, including gathering information, analyzing and interpreting, and responding to stimuli.

Explanation

The correct answer describes the major functions of the nervous system accurately, including gathering information, analyzing and interpreting, and responding to stimuli.

2. What are the different types of nerves?

Cranial (related to the brain)

Sensory (outside to the brain = afferent)Intergration (interneuron)Motor (brain to outside = efferent)

Autonomic (involuntary control)

Peripheral (around the body)

The correct answer includes the three main types of nerves: Sensory, Integration, and Motor. Peripheral, Autonomic, and Cranial nerves do not represent the primary categories of nerves.

Explanation

The correct answer includes the three main types of nerves: Sensory, Integration, and Motor. Peripheral, Autonomic, and Cranial nerves do not represent the primary categories of nerves.

3. Describe the organisation of the nervous system in words.

The motor division conducts afferent impulses to the CNS through the peripheral nervous system.

The autonomic system is split into three divisions including the Sympathetic Division, Parasympathetic Division, and Neutral Division.

The sensory division is responsible for mobilizing body systems to deal with daily stress.

The correct answer describes the flow of information within the nervous system, emphasizing the roles of sensory and motor divisions, as well as the autonomic system. The incorrect answers either provide inaccurate information or mix up the roles of different divisions within the nervous system.

4. How is the brain protected?

Bone, meninges and cereospinal fluid.Harmful substances are shielded from the brain by the blood-brain barrier

The lungs provide a protective barrier for the brain

The skin acts as the main protection for the brain

The brain is not protected and is exposed to all harmful substances

The brain is protected by multiple layers such as bone, meninges, cereospinal fluid, and the blood-brain barrier. These structures help shield the brain from harmful substances and provide necessary protection for its proper functioning.

5. What are the three connective tissues membranes that lie external to the central nervous system?

Synovial membrane, Periosteum, Endothelium

The meninges. Dura mater, Arachnoid mater, and pia mater

The meninges are the three protective membranes that cover the brain and spinal cord. These membranes are composed of the dura mater, arachnoid mater, and pia mater, which provide support and protection to the central nervous system.
