communication system which delivers information to and from the brain and spinal cord and all over the body. In any nervous system‚ there are 4 main components: (1) sensors: gather information from the external environment (sense organs) (2) conductors: carry information from sensors to modulators or from modulators to effectors (nerves) (3) modulators: interpret sensory information and send information to effectors (brain‚ spinal cord) (4) effectors: part of the body that responds because of information

1. Describe Ossification during Fetal Development. Ossification is the formation of bone and in a fetus is made up of cartilaginous tissue. This tissue is less dense than that of bony tissue. Over time‚ as calcium salts are being deposited into the cartilaginous tissue by immature bone cells‚ the formation of bone occurs. 2. What are the roles of Osteoclasts in bone formation? Osteoclasts reabsorb bony tissue from the innermost part of the bones‚ allowing for a larger cavity‚ in order to avoid

Biological Bases of Behavior Nervous System Made up of neurons‚ which are the nerve cells. These send electrical impulses to one another ( through a process known as firing) telling the body what to do. The parts of a neuron include: Cell Body (a.k.a. soma) – Main part of neuron; contains basic cell parts such as nucleus‚ ER‚ etc.; also has dendrites extending from it. Dendrites – bushy fibers which extend from the soma; receives impulses and directs them towards soma Axon – an extension

Neuroscience: Neurotransmitters (small molecule and neuroactive)‚ storage release removal and disease. 1. The brain is made up of neurons that process and transmit information by electrochemical signaling. Neurotransmitters are endogenous chemicals which relay‚ amplify‚ and modulate signals between a neuron and another cell. Chemical messengers must fulfill four criteria to be considered a transmitter. These four steps include the synthesis of a transmitter substance‚ the storage and release of

Over the course of history‚ people have been awed by the power and complexity of the human behavior‚ but it wasn’t until the 19th century that psychology became a real science. At first‚ it was hard to determine how psychology would interpret human behavior and the wonders of the mind. Originally it was thought to be a part of philosophy. However‚ after years of research‚ some psychologists decided they did not want to be part of philosophical world and commit themselves to full scientific psychological

Discussion In the patellar reflex experiment‚ the class results have shown the reaction is faster with performing the Jendrassik’s maneuver. Our group hypothesis was proven incorrect. The source of error in this experiment would be the subject can easily control the skeletal muscles which would be voluntarily because the subject was not blindfolded. Therefore‚ the subject can see the rubber coming at their knee and is expecting the knee to jerk. It’s hard to consider this exact result when the subject

Another one of the important connections would be the control center‚ or also known as the nervous system. The brain controls the body’s decision and communication throughout‚ the nervous system. The nervous system is made of the brain and the spinal cord. It also includes the peripheral nervous system which is made of the nerves. Working together‚ they both control everything that happens in our daily life’s‚ like breathing and blinking‚ memorizing facts for a test‚ and the beating of our heart
