different function. This includes the brain stem which connects to the spinal chord. 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

Body Systems of Various Organisms All organisms in the world have a range of systems and organs in their body. Some organisms may share similar body systems while others have absolutely nothing in common. Several of those organisms include humans‚ pigs‚ crayfish‚ and earthworms. From their mushy‚ gushy organs to their soft‚ gentle skin‚ you may think‚ “How are humans and pigs possibly alike? Or a crayfish and an earthworm?” In many ways they may not be‚ but in other ways‚ they are very much alike

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

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

Foster Collage of Physical Education & Sports Mr. April 13‚ 2015 What is the Neuromuscular System? According to research the neuromuscular system is to make the body move‚ a signal travels along neurons nerve cells from the brain to the spinal cord. There‚ "lower motor neurons" pass the message on to the muscles. The end of every lower motor neuron releases a chemical‚ which is
