The building blocks of our body ’ s neural information system are neurons. Each neuron is composed of dendrites‚ a cell body‚ axon with myelin sheath‚ and vesicles with neurotransmitters. The neuron receives information from sense receptors or from chemical messages from neighboring neurons via its dendrites‚ which pass the information to the cell body. The cell body fires an impulse‚ called the action potential‚ down the axon. The impulse is protected and sped along its way by the myelin sheath

skeleton is often described as a solid‚ moveable framework that supports the body. Bone is a strong and rigid form of connective tissue. It also works as levers and anchor plates to allow movement to take place. Bones also work for alternative body systems for example the blood cells develop in their fatty inner tissue (red marrow). The body draws from mineral stores in bones during crucial times of shortage‚ for instance when calcium is needed for healthy nerve functioning. The skeletons key components

The brains stem helps to perform basic functions for humans like heart rate‚ breathing‚ digesting food‚ and for sleeping. You can locate the brainstem below the limbic system. The Brainstem contains the pons and medulla. The pons is above the medulla and helps to perform motor control like sounds are transferred from the ear to the brain through the pons. It also helps with your consciousness and sleep. The pons is linked

The brain develops very quickly 75% by age 2. Describe the brain’s communication system and all of the individual parts associated with this. Neuron‚ axon dendrite‚ synapse‚ neurotransmitter and receptor. Also include transient exuberance. Neuron consists of a cell body and branching fibers. Neurons can communicate by firing chemical or electrical signals. It is excitable and can transmit and process information through electrical and chemical signals. Those signals occur in synapses. Synapses are

Aging in the brain is a complex process that involves several systems and structures. Normal aging not only shows a decreased activity in neurotransmission‚ but also is a major risk factor for the development of neurodegenerative diseases. Dysfunction of the central noradrenergic and dopaminergic systems is one of the biological characteristics of aging‚ which may contribute to changes in cognitive and motor functions in aged persons. Furthermore‚ aging-dependent norepinephrine (NE) loss occurs earlier

Patriarchal oppression is one of the major themes in Dangarembga’s Nervous conditions. According to Dambe 2014‚ patriarchy refers to a system of practices and structures in which men have more power than women and are able to use their power to dominate and oppress women. It is this patriarchal distribution of power that puts women in all kinds of dilemmas in the novel. One of weapon men use to oppress women is “silence and obedience’. Silence and obedience are considered as important values in Shona

The Limbic System Most reptiles and lower order organisms only have the “old brain”‚ the evolutionarily oldest part of the brain responsible for vital tasks such as breathing and sleeping‚ whereas higher order organisms have a limbic system. The old brain is comprised of the pons‚ the medulla oblongata‚ the brain stem‚ the thalamus‚ the cerebellum‚ and the reticular formation. The reticular formation is a network inside of the brain stem‚ part of the “old brain” that is essential for arousal (sleeping
