Gateway of consciousness

Question 6

Thalamus is a part of what part

Answer 6

Part of diencephalon

Question 7

Senses received by Thalamus

Answer 7

All senses (except olfactory) are processed and filtered by it before they reach the ipsilateral NEOcortex {Theneocortex, also called theneopallium,isocortex, or thesix-layered cortex, is a set of layers of themammaliancerebral cortexinvolved in higher-order brain functions such assensory perception, cognition, generation ofmotor commands,[1]spatial reasoningandlanguage.[2]The neocortex is further subdivided into thetrue isocortexand theproisocortex.[3]}

Question 8

Corpus callosum

Answer 8

Exchange of information and coordination between two hemisphere
(e.g.So the left hand knows what the right hand is doing)

Question 9

Hypothalamus control what

Answer 9

It controls automatic nervous system (e.g. regulate correct setting of body temperature and blood pressure. also controls thirst and hunger

Question 10

Answer 10

Hippo campus
Amigdala
Fornix with mammillary body in front

Question 11

Location of limbic system

Answer 11

Deep into the cerebrum

Question 12

Function of hippocampus

Answer 12

Memory formation

Question 13

Function of amygdala

Answer 13

Store information about danger

Question 14

What will happen if hippocampus is destroyed or removed

Answer 14

Person Will unable store new memories

Question 15

Cerebellum

Answer 15

Is smaller than cerebrum but higher cellular density

Question 16

Most important Nerve cell in cerebellum

Answer 16

Purkinje cell which can be regarded as most complex neuron in entire nervous system

Question 17

Function of cerebrum

Answer 17

It is able to transform planned movement pattern of cerebrum into coordinated movement sequences and without is our harmonious movement like walking will not be possible

Question 18

Pituitary is a Part of …

Answer 18

Diencephalon

Question 19

Function of pituitary gland

Answer 19

Hormonal regulation of growth, metabolism, reproduction

Question 20

Control of sleep wake cycle

Answer 20

By pineal gland also known as emphasis cerebri by secretion of melatonin hormone

Question 21

Content of vertebral column

Answer 21

Fatty tissue
Connective tissue
Spinal cord

Question 22

How does arachnid matter connect pia mater

Answer 22

Via arachnoid trabeculae

Question 23

Content of spinal nerve

Answer 23

Blood vessels
Nerve fascicles
(A nerve fascicle is a bundle of nerve fibers belonging to a nerve in the peripheral nervous system.[1] A nerve fascicle is also called a fasciculus,[2] as is a nerve tract in the central nervous system.)

Question 24

Enclosing connective tissues of spinal nerve

Answer 24

From within outwards
1.Nerve fibers are endless by endoneurium ( Swann cells are located under this protected later. These cells increase conduction speedb with hello of regular interruptions called nodes of Ranvier
2. Fascicles are enclosed by perineurium
3. Never thunk stroma and covering is epineurium

Question 25

Presynaptic terminal knobs

Answer 25

They are located at the end of axons. They contain calcium channels which open via electrical impulse and allow calcium ions to follow in. There are approximately 200-500 neurotransmitters containing vesicles within terminally knobs. Calcium ions enable this vesicle to fuse with membrane causing exocytosis of neurotransmitter. Neurotransmitters are absorbed by receptors located at post synaptic membrane of dendrites which convert the neurotransmitter back into electrical impulse. Terminal buttons can also transmit impulses directly on cells,muscles, another axons or terminal button

Question 26

Postsynaptic spines

Answer 26

They are part of the dendrites for receiving signal from another nerve cells.The spines can be of many forms including stubby and thin.

Question 27

Dorsal root ganglion

Answer 27

Contain cell bodies of sensory neuron which are pseudounipolar(axon is divided into two branches, one at periphery and other at CNS

Question 28

Orders of neuron for sensation via spinal cord

Answer 28

First order: sensory neuron via axon from periphery to another neuron in spinal cord Second order: neuron in spinal cord transmitting implied to brain Third order: another neuron from here to the somatosensory cortex The impulse is then processed.

Question 29

Receptors in skin

Answer 29

Superficial in epidermis 1. Meissner's corpuscles: pressure 2. Merkel cell: pressure Deep in dermis 1. Ruffini corpuscles: stretch

Question 30

Question 35

Function of cerebrum

Answer 35

Making a sender of information Lateralization of the brain (e g. LEFT: meaning right handed) is dominant in some functions like mathematical reasoning, logic, facial recognition, things we put on the right side etc. But these are plastic meaning we can do these with the counterpart too
