A minicomputer is the term given to any computer small enough to be portable. Usually, these are laptops, and they can mostly function like regular computers, albeit with less processing power.

The basic unit of the nervous system is the neuron. Neurons are specialized cells that transmit signals in the form of electrical impulses to communicate information throughout the body. They have a cell body, dendrites to receive signals, and an axon to transmit signals.

The nervous system coordinates the work of the body by sending electrical signals called nerve impulses to different parts of the body through neurons. These signals help regulate and control various functions such as movement, sensation, and organ function. The brain and spinal cord are key components of the central nervous system that process and interpret these signals to ensure proper coordination of the body's activities.

Sources of stimulation that can start a nerve impulse include chemical signals (neurotransmitters released at synapses), physical stimuli (such as pressure or temperature changes acting on sensory receptors), and electrical signals (generated by neighboring neurons or external electrical sources). These stimulations can trigger the opening of ion channels in the neuron's membrane, leading to changes in membrane potential and initiation of an action potential.

The two divisions of the nervous system are the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which includes all the nerves outside the CNS that relay information to and from the brain and spinal cord.

1. Resting potential: all voltage-gates are closed. 2. At threshold, Sodium activation gate opens and Sodium permeability rises.

3. Sodium enters the cell (influx), causing an explosive depolarization to +30 mV, which generation the rising phase of action potential.

4. At peak of action potential, sodium activation gate closes and sodium permeability falls, which reduces the net movement of sodium into the cell. At the same time potassium activation gate opens and potassium permeability rises. .

5. Potassium leaves the cell (efflux), causing the repolarization to resting potential, which generates the falling phase of action potential.

6. On return to resting potential, sodium activation gates closes and inactivation gates opens, resetting channel for another depolarizing triggering event.

7. Further outward movement of potassium through still open potassium channels briefly hyperpolarize membrane,

8. Potassium activation gate closes and membrane returns to resting potential

Both G-protein receptor system and Tyrosine-kinase receptor system are involved in cell signaling pathways and regulate various cellular processes. They both have the ability to transmit extracellular signals to the inside of the cell, resulting in cellular responses. However, they differ in their mechanisms of action and the types of intracellular signaling pathways they activate.

There is some evidence to suggest that psychopaths may have differences in autonomic nervous system functioning compared to non-psychopathic individuals, such as reduced fear responses. However, more research is needed to fully understand the relationship between psychopathy and autonomic arousal.

the circulatory system contains blood vessels, heart, arteries. the three main functions of the circulatory system is to deliver blood in and out of the heart, it helps the blood cells carry nutrients to the rest of the body, thats all.=)

The somatic nervous system is responsible for the voluntary control of skeletal muscles and the perception of external stimuli such as touch and pain. It coordinates body movements and processes sensory information to help us interact with our environment.

A burette can be used in an infusion system to accurately measure and control the flow rate of fluids being administered to a patient. This allows healthcare providers to precisely titrate medication or fluids based on the patient's needs and helps prevent overinfusion or underinfusion.

Ventilation is controlled by the respiratory centers in the brainstem, which monitor factors like blood pH, carbon dioxide levels, and oxygen levels to regulate breathing rate and depth. When demands on the body change, such as during exercise or when oxygen levels decrease, the respiratory centers adjust ventilation to meet the body's needs.

The deterioration of the nervous system and tremors can be caused by various conditions such as Parkinson's disease, multiple sclerosis, or essential tremor. Treatment depends on the underlying cause and may involve medication, therapy, or surgery to manage symptoms and improve quality of life. While there may not be a cure for some conditions causing these symptoms, treatments can help alleviate symptoms and slow disease progression.

The basal ganglia are a group of structures in the brain involved in the coordination of movement, as well as aspects of behavior and cognition. They work with other brain regions to regulate voluntary motor control and procedural learning. Dysfunction in the basal ganglia can lead to movement disorders such as Parkinson's disease and Huntington's disease.

The three main functions of the lymphatic system are fluid balance, immune defense, and lipid absorption. It helps to maintain fluid balance in the body by draining excess fluid from tissues, supports the immune system by producing and transporting white blood cells, and absorbs fats and fat-soluble vitamins from the digestive system.

Nerves function to transmit signals between the brain and other parts of the body, allowing for the coordination of movement, sensation, and other physiological processes. They can also regulate involuntary functions such as heartbeat and digestion. Damage to nerves can lead to loss of sensation, muscle weakness, or altered bodily functions.

Excitatory neurotransmitters stimulate the receiving neuron to generate an action potential, leading to the propagation of a nerve impulse. They increase the likelihood of the neuron firing and are essential for normal brain function and communication between neurons. Examples include glutamate and acetylcholine.

Electrical conductivity is important because we live in a world that is increasingly run by electronic devices. These devices depend on materials that are electrically conductive to send their signals and operate.

A reflex action is an involuntary or automatic response to a stimulus, usually to protect the body from harm. It does not involve conscious thought and typically involves a specific neural pathway. Examples include the knee-jerk reflex and withdrawing your hand from a hot surface.

The bicarbonate buffer system is an important buffering system in the human body. It helps regulate the pH of the blood by maintaining a balance between carbonic acid and bicarbonate ions. This system plays a crucial role in preventing drastic changes in pH that could be harmful to the body's metabolic processes.

The digestive and nervous systems work together in several ways. The nervous system controls the muscles involved in swallowing and peristalsis, which moves food through the digestive tract. It also regulates the release of digestive enzymes and hormones. Additionally, the digestive system sends signals to the brain to indicate hunger or fullness, which are important for regulating food intake.

There are many different cells in the human body. The different cells in the body are generally grouped into tissues that have similar properties. The four main groups of tissues in the body are, muscular, nervous, connective, and epithelial.

There are 3 classes of cells in the human body. Labile cells, stable cells, and permanent cells. Labile cells are dividing all the time--always in the cell cycle. Examples include cells in the digestive tract, skin, respiratory tract, and stem cells in the bone marrow producing blood cells. Stable cells are in Gap O most of the time in the cell cycle, but can be stimulated to enter the cell cycle when needed. Examples include: the liver, the proximal tubules of the kidney, and endocrine glands. Permanent cells remain in the Gap 0 phase of the cell cycle, and will not come out no matter what!!! RBC's, nervous tissue, cardiac myocytes, and the lens of the eye are examples. Permanent cells cannot be replaced!!

The nervous system plays a role in controlling the rate and depth of breathing through signals sent to the respiratory muscles. Nerves in the brainstem regulate automatic breathing, while the somatic nervous system controls voluntary control of breathing. Feedback from the respiratory system also influences the nervous system's regulation of breathing.

The medulla oblongata is responsible for controlling vital autonomic functions such as blood pressure, heart rate, breathing, and swallowing. It also serves as a relay center for sensory and motor pathways traveling between the brain and spinal cord.

The nervous system regulates heart rate and blood pressure through nerve signals sent to the heart and blood vessels. Additionally, the circulatory system provides the brain and other organs with the necessary oxygen and nutrients for optimal nerve function. Overall, the two systems work together to coordinate and maintain bodily functions.
