Define phrenology. How did phrenology suggest the modern-day idea of LOCALIZATION OF FUNCTION Phrenology-the detailed study of the shape and size of the cranium as a supposed indication of character and mental abilities. Phrenology is a process that involves observing and/or feeling the skull to determine an individual’s psychological attributes. The idea that different parts of the brain do different things is called localization of function. Phrenology could have been used to feel the bumps on

Nervous tissue This tissue is found in the spinal cord‚ the brain and the nervous. The nervous tissue is seen as the ‘brain’ of the tissues as it is responsible for all informational functions. The nervous tissue contains neurons‚ and these neurons can never divide therefore can never be replaced if/ when they die. The functions of the nervous tissue are to receive nutrients from our blood‚ however it is protected in a shell so cannot receive all of the nutrients.

The nervous system possesses three main cell types‚ one of which being the neurons. These are formed of different elements‚ the axon‚ cell body and dendrites. Axons play an important part in the fast reaction for survival. The wider the axon‚ the faster it will conduct the action potentials. For example‚ the squid carries a particular neuron involved in the escape response from danger. The axon from this specific neuron has quite a wide diameter‚ which makes it conduct action potentials faster.

but it also controls the body’s voluntary movements as well. These movements include posture‚ balance‚ speech‚ and coordination. When compared to the size of the cerebrum it is much smaller in weight‚ but it contains about half of the brain’s total neurons. With this high volume of sensory cells‚ it is known that this organ is vital to all of the movements that one needs to make. If damage is done to the cerebellum‚ one would not become paralyzed or their intellect compromised‚ but their motor functions

Neurological Processes PSY/340 Neurological Processes Every animal has a brain‚ but humans have a more complex and unique brain in terms of giving individuals the power to think‚ plan‚ speak‚ act‚ and behave. It is an extremely complex organ that consists of many areas that all work together in unison in order for the body to perform the tasks it is told to perform. The brain is responsible for controlling both voluntary and involuntary actions and coordinates and controls other organs in the

Running Head: Biological Psychology Paper Biological Psychology Paper Biological Psychology Paper Biological psychology is a vital part of psychology; without it psychology would not be considered a science‚ rather it may still be considered an art. Biological psychology has an extensive history‚ and each step has brought us closer to the reality that the brain is our main power source‚ and how much it affects our behavior. There have been many scientists and theorists that have contributed

different parts. The video describes the three important jobs our neurons do: receive information from other cells‚ process information‚ and transmit it to the rest of the body. Without our neurons we would have no brain activity. All behavior begins with an action from a neuron. First the brain gathers information from the receptors and spread it around it’s branch fibers‚ or dendrites. Next the information is sent to the soma‚ the neurons cell body‚ where it is combined with other information. Finally
