Some of the most dangerous hazards in this world are the outcome of purely voluntary behavior – in particular, smoking tobacco and engaging in risky sexual activity. We will look at four […]

1. Why don’t the terms depolarization and action potential mean the same thing? The terms depolarization and action potential differ because are excitable cells that communicate by transmitting electrical impulses that are capable of producing rapid electrical signals and depolarization in the interior surface of the membrane which becomes less negative and the exterior surface […]

Naked Mole Rats possess anatomical, physiological, and behavioral features that are distinct from most mammals. They have incisor teeth for chewing on tough, fibrous plant materials and digging, lack of fur and reduced eyes, and soldiers that defend the colony against predators and rivals instead of fleeing. Unlike most mammals, Naked Mole Rats lack features […]

A motor unit controls a muscle fiber and consists of a motor neuron. A muscle comprises numerous motor units managed by distinct motor neurons which react to different levels of stimulation. Electric shock changes membrane permeability to permit passage of sodium and potassium ions which act as an action potential. As the motor neurons stimulate […]

The spinal cord, which is 43cm long, is encased in the vertebrae and is the main communication cable between the CNS and the PNS. ‘The nerve fibres running from various parts of the body to and from the brain are gathered together in the spinal cord, where they are protected by the bony spinal vertebrae.’ […]

Neurotransmitters are chemicals that communicate between nerves. In some ways, neurons are like computers: they receive messages, process those messages, and send out the results as new messages to other cells. In the case of neurons, messages consist of chemicals that interact with the outer surface of the cell membrane. This chemical interaction with the […]

Communication is the process of sharing information or ideas between individuals or groups. Communication takes place in different contexts, such as phone conversations or face-to-face discussions, where information is exchanged between different locations. Similarly, within the human body, information transmission plays a vital role in decision-making and action execution. For example, when an individual touches […]

Introduction Neurons are the cells that receive and transmit electrical signals. The ability of the neuron to conduct these impulses is because of an electrochemical voltage across the plasma membrane of that neuron. An action potential is an all or nothing response to a stimulus along a single axon. A compound action potential is a […]

Campbell’s AP Biology Notes Chapter 48: Nervous Systems Command and Control Center The human brain contains an estimated 100 billion nerve cells, or neurons Each neuron my communicate with thousands of other neurons Functional magnetic resonance imaging (fMRI) is a technology that can reconstruct a 3-D map of brain activity The results of brain imaging […]

For this lab, report your observations in a formal report, according to the formatting prescribed in Lab Report Format. doc which is found on Blackboard under Assignments/Before You Begin. Equipment needed: Metal calipers or compass with pencil 2 or more blunt probes […]

A neuromuscular junction is a place in the body where the axons of motor nerves meet the muscle, thus transmitting messages from the brain which cause the muscle to contract and relax. Every organism has thousands of neuromuscular joints which are the locations and means by which the motor neuron of the nervous system that […]

The human body is a tremendous creation that is quite capable of performing a multitude of multifaceted movements and thoughts.
