Question

Hello friends...★Quality answer required★ Hope u will give quality answer,,, classify the nervous system and write in detail about functional areas of cerebrum..marks-12...don't copy from internet

Answer 1

*nervous system is of two types
- central nervous system__ it includes brain and spinal cord
- peripheral nervous system__ it includes cranial nerves and spinal nerves
*Peripheral nervous system is of two types
-somatic nervous system__ itralase the impulse from CNS to skeletal muscle
- autonomous nervous system__ itralase the impulse from CNS to smooth muscle and glands
*autonomous nervous system is of two types
-sympathetic nervous system and__ it helps to increase the activity of visceral organs and glands
- parasympathetic nervous system__ it helps to decrease the activity of visceral organs and glands

Brain-Cerebrum
cerebral consists of four lobes
-frontal lobe
-perital lobe
-temporal lobe
-occipital lobe
function areas of cerebrum:-
PLEASE REFER TO THE PICTURES.. If you want more details

Hey dear here is your answer!!!!!

*********************************************

The nervous system is classified into :-

1) Central Nervous System (CNS)
2) Peripheral Nervous System (PNS)

_________________________________

1) Central Nervous System:-

The central nervous consistent of part of our brain and spinal cord . It is referred as "central" because it combines information from the entire body and coordinates activity across the whole organism .

The brain is protected by skull ( the cranial cavity) and the spinal cord travels from the back of the brain , down the centre is spine .

The brain and spine are both housed within a. protective tripled layer membrane called meninges .

2) Peripheral Nervous System:-

The peripheral nervous system (PNS) consists of all neurons that exist outside the brain and spinal cord. This includes long nerve fibers containing bundles of axons as well as ganglia made of neural cell bodies. The peripheral nervous system connects the central nervous system(CNS) made of the brain and spinal cord to various parts of the body and receives input from the external environment as well.

Functionally, the PNS is divided into sensory (afferent) and motor (efferent) nerves, depending on whether they bring information to the CNS from sensory receptors or carry instructions towards muscles, organs or other effectors.

__________________________________

The cerebral cortex is divided into sensory, motor and association areas. Sensory areas receive sensory input, motor areas control movement of muscles. Association areas are involved with more complex functions such as learning, decision making and complex movements such as writing.

The central sulcus divides the primary sensory and motor areas. Both the sensory cortex and the motor cortex have been mapped out according to what part of the body it controls. A larger portion of the cortex is involved with the lips, face, and fingers which contain a greater number of sensory receptors.

Broca’s area, the motor speech area, is involved in translating thoughts into speech

The visual area receives visual stimuli and the visual association area helps to interpret those stimuli. It is also involved with memory and recognition.

The auditory area receives auditory information. The auditory association area is where sound is interpreted as noise, music or speech.
