Paste an image found on LabPaq site or Google images of a spinal cord smear and label its basic parts using basic labeling boxes provided. Identify the cell body, the nucleus, the large nucleolus, and granular Nissl bodies on the slide. Try to find the axon and differentiate it from the dendrites if possible. Hint: after pasting image, right click on it and select “order”, “send to back”.…
Recruitment of the nerve’s neurons. Increasing the voltage will cause most of the neural fibers to experience depolarization.…
The communication process of neurons in the brain occurs through an electrochemical process. Neurons pass neurotransmitters through the dendrites, which are attached to the ends of each neuron and receive messages from neighboring neurons. The chemical messages that are passed from one neuron to the next cause an action potential. This occurs when the receiving neuron accepts the right amount of the correct message. Once the message is received, the neuron will then send neurotransmitters to the next neuron through the axon. After the neurotransmitters pass through the axon they are released through the terminal buttons.…
Neurons (also known as neurons, nerve cells and nerve fibers) are electrically excitable and the most important cells in the nervous system that functions to process and transmit information. Neurons have a large number of extensions called dendrites. They often look likes branches or spikes extending out from the cell body. It is primarily the surfaces of the dendrites that receive chemical messages from other neurons.…
Neuron cells are the information processing components of the brain responsible for receiving and transmitting information. Each part of the neuron plays a role in the communication of information throughout the body.…

Although the brain was once seen as a rather static organ, it is now clear that the organization of brain circuitry is constantly changing as a function of experience. These changes are referred to as brain plasticity, and they are associated with functional changes that include phenomena such as memory, addiction, and recovery of function. Recent research has shown that brain plasticity and behavior can be influenced by a myriad of factors, including both pre- and postnatal experience, drugs, hormones, maturation, aging, diet, disease, and stress. Understanding how these factors influence brain organization and function is important not only for understanding both normal and abnormal behavior, but also for designing treatments for behavioral…
At birth there are about 100 billion brain cells produced and they are beginning to connect with each other. At the first week of age, brain development starts with conception. It is important to reach the age of an infant and practice the ten principals. In the early years, young brains produce almost twice as many synapses as they will need. By age two, the number of synapses a toddler has is similar to that of an adult. By three the child has twice as many synapses as an adult. The infant brain develops through the interaction with the world around, especially the interaction with adults. At the first few months, an infant cannot response to praise or punishment. Emerging research on brain development indicates that the degree for responsive care giving that children receive as infants and toddlers positively affects the connections between neurons in the brain (Brain Cells), and the architecture of the brain itself. The first three years of life are the period of growth in all areas of a baby’s development. Consistent, responsive relationships enable infants and toddlers to develop secure attachments (ZERO TO THREE).…
Similarly to these concepts, neuroplasticity lets the brain to grow and make new connections. Neuroplasticity allows the brain to adapt to new environments and changes it physically and functionally. When the brain is exercised like a muscle, it becomes stronger and more powerful. Brain capacity can be increased with challenges and by performing complex problems.…
It is not commonly known that the brain is 90% developed by age five. Most people believe that at age five children are just starting to learn. In fact, the brain absorbs more from birth to age five rather than from age five on. Parents and family can do many things to aid in the development of a baby’s brain, ultimately assisting in their learning. The sequence and rate at which the brain develops predicts the optimal times for a baby to learn. Sequence and rate is measured by milestones that a baby may reach by a certain age. Experiences are one thing that helps promote brain development. Our five senses give us these experiences. How in the first few years of life do we develop into the complex people we are today? We will look at how nature versus nurture; sensory perception; positive and negative experiences and both our social and physical environment contribute to and develop everything about whom we are as individuals.…
Child development is crucial throughout the early years, during this time the development of the brain occurs and continues through late adulthood. The development of the brain contributes to the functioning of the body. The anatomy of the brain is made up of neurons and divided into four different lobes. The temporal, frontal, parietal, and occipital lobes control a variety of cognitive functions (Santrock, 2013). The brain controls simple functions such as fine and gross motor skills, vision, and memory. For instance the frontal lobes are involved in the voluntary movement, thinking, personality, and intentionality or purpose. The occipital lobes are responsible for vision. The temporal lobes are responsible for hearing, language processing and memory. The parietal lobes plays role in registering spatial location, attention and motor control. (Santrock, 2013). Brain development in children is vital during the early years. During the early years, children brains are active enabling children to learn a variety of information. However, as individual ages there are changes in the brain which influence cognitive functioning learned throughout the years of development.…

The human brain has the amazing ability to reorganize itself by forming new neural connections throughout life. Neuroplasticity or brain plasticity as it is also known as, occurs during development in childhood, following a physical injury, such as loss of a limb or sense organ, and during reinforcement of sensory information such as in learning. It is with this brain’s ability that the human being is constantly able to progress in life, mentally and when stricken with disease to physical injury affecting the brain, to adjust and adapt, for it is the brain that can find a way, even if having to redirect a new route. What neuroplasticity refers to is, neurons (nerve cells) in the brain compensating and altering their activities in response to new situations or to changes in their environment. These alterations entail having to change the neural pathways and synapses as a result of any of the above mentioned examples.…
