The peripheral nervous system contains all of the following except .

Explanation:

The nervous system is divided into two parts: central nervous system formed by the brain and spinal cord and peripheral nervous system that is formed by nerves and nerve ganglia that extend outside the central nervous system. The main function of thenervous system Peripheral is to connect the central nervous system with the limbs and organs. It lacks protective bone lining which differentiates it from the central nervous system that is enveloped by the skull and spine.

In the human species it is composed of 12 pairs of cranial nerves and 31 pairs of spinal nerves, thus giving a total of 43 pairs of nerves. Each of the nerves follows a defined path and innervates a specific sector of the body. The division between central nervous system and peripheral nervous system is anatomical or structural. From a functional point of view, the peripheral nervous system can be divided into a somatic nervous system that is controlled voluntarily and an autonomous nervous system that works involuntarily or automatically.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
