Alvaro Comino LAB REPORT 4 CONNECTIVE TISSUE (SPECIALIZED) I. Abstract In this experiment‚ identification and classification of different types of connective tissue was performed. Also‚ cells and extracellular matrix was to be identified in them. For this‚ different already prepared slides were chosen and observed under the microscope to then identify the different parts. II. Introduction Apart from the bone and cartilage‚ the rest of the specialized connective tissues are divided

APPROACH AND RECENT BRAIN RESEARCH 2 Abstract New technological advances in brain research allow scientists better understanding of how the brain develops. From birth‚ the task of the brain is to establish and reinforce connections between neurons. Dr. Montessori’s approach on brain development in young children coincides with much of the most recent brain research. Dr. Montessori discovered from her observations that the early years of a child’s life is the period when the brain’s capacity

Neurotransmitters Dr. C. George Boeree Neurotransmitters are the chemicals which allow the transmission of signals from one neuron to the next across synapses. They are also found at the axon endings of motor neurons‚ where they stimulate the muscle fibers. And they and their close relatives are produced by some glands such as the pituitary and the adrenal glands. In this chapter‚ we will review some of the most significant neurotransmitters. Acetylcholine Acetylcholine was the first neurotransmitter

randomly vs. fixed time intervals‚ and upon repetition. Introduction Our bodies react appropriately to changes that occur in the environment during our day-to-day activities. When responding‚ an external stimulus has to be detected by one or more neurons. These then send this sensory information to the nervous system where processing occurs. If a motor signal is started‚ it usually involves a number of action potentials‚ which lead to muscle contraction and movement of other parts of the body in reaction

Neurodegenerative diseases is a common cause of dementia which means that the brain cells known at the neurons either are degenerating therefore the neuron die off quicker than that of the neurons of a normal aging processes. This will lead to a more decline in the persons mental health such as memory‚ language and sometimes their physical abilities all depending on which area of the brain is infected. These neurodegenerative diseases are known to us as Alzheimer’s‚ fronto-temporal dementia‚

Much like cells are the fundamental unit of a living being‚ neurons are the fundamental unit of the nervous system. These neurons work together with other excitable cells to produce action potentials when they receive electrical or chemical stimuli. Action potentials can be thought of as an “all-or-nothing” event and occur as a large-scale depolarization when sodium and other positive ions rapidly enter the neuron through membrane channel proteins. Once initiated‚ action potentials travel down the
