It was used again in in a work entitled Philosophiae naturalis sive physicae: The first German use, Biologie, was in a translation of Linnaeus' work.
The nerves, muscles, and joints must work together in a chain to produce motion kinetic. These three systems are also referred to as the kinetic chain. Billions of neurons make up nervous system, provides it with ability to communicate internally with itself as well as externally with environment.
Transmits impulses through both electrical and chemical signals. Forms the core of the nervous system which includes the brain, spinal cord, and peripheral ganglia. Neurons are composed of cell body, axon, and dendrites.
The cell body of Neuron contains a nucleus, lysosomes, mitochondria, and a Golgi complex.
Axon — cylendrical projection from the cell body that transmits nervous impulses to other neurons or effector sites muscles, organs.
Provides communication from brain and spinal cord to other parts of the body. Dendrites — gather information from other structures and transmit it back into the neuron. So sensory neurons transmit from muscles and organs to the CNS.
Motor neurons transmit nerve impulses from CNS to muscles and organs. Interneurons transmit impulses between neurons. Nerves of PNS are how CNS receives sensory input from sensory afferent neurons and initiates responses through motor efferent neurons.
The PNS serve two main functions. They provide a connection for the nervous system to activate different effector organ, muscle sites. Second they relay information from effector organ, muscle sites back to the brain via sensory receptors, providing constant update to the relation of the body and the environment.
The PNS consists of the somatic and autonomic nervous system.
The somatic nervous system consists of the nerves that serve the outer areas of the body and skeletal muscle and are responsible for the voluntary control of movement.
So somatic is what controls your biceps and legs and whatnot. The autonomic nervious system supplies neural input to the involuntary systems of the body, like your heart.
The autonomic is divided into sympathetic and parasympathetic nervous systems. The sympathetic system increases the activation level of neurons in preparation for activity ramps you up.
The parasympathetic ramps your system down, decreases levels of activation. Sensory receptors are specialized structures that convert environmental stimuli heat, sound, taste, etc into sensory information for the brain.
These receptors are divided into four categories, mechanoreceptors, nociceptors, chemoreceptors, and photoreceptors. Respond to outside forces such as touch, pressure, stretching, sound waves, and motion. Senses distortions in body tissues.
Help regulate the contraction of muscles via the stretch reflex mechanism. This mechanism is a normal response to the body to a stretch stimulus in the muscle, it is designed to protect and prevent overstretching and muscle damage. Sensitive to changes in muscular tension and rate of tension change.
Activiating the Gogli tendon organ causes the muscle to relax which prevents the muscle from excessive stress or injury.
Signals extreme joint positions and thus helps prevent injury. Performance increases in early stages of training result from changes in the way the CNS controls and coordinates movement. Unsuccesful performances can be cross referenced with other sensory input and new movement strategys found.
Regular training causes adapations int he CNS, allowing greater control of movements, thus causing movements to be more smooth and more accurate — improving performance. Provides shape and focus for bodies. Produces blood for the body and stores minerals. Growth, maturation, and functionality of skeletal system are greatly affected by posture, physical activity, and nutrition.Chapter 1 Introduction to Anatomy and Physiology An understanding of the structure (anatomy) and function (physiology) of the human body is important in the life of.

Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution.
Despite the complexity of the science, there are certain unifying concepts that consolidate it into a single, coherent field. Biology recognizes the cell as the basic unit of life, genes as.
