1.An extensive network of specialized cells that carry information to and from all parts of the body is called the nervous system. 2.The basic cell that makes up the nervous system and which receives and sends messages within that system is called a neuron. 3.The long tube-like structure that carries the neural message to other cells on the neuron is the axon. 4.On a neuron‚ the branch-like structures that receive messages from other neurons are the dendrites. 5. The cell body of the neuron‚ responsible

Ch 11 Vocabulary Anesthesiologist- is a physician who specializes in anesthesiology. Auditory/Eustachian tube - is a tube that links the nasopharynx to the middle ear. Auricle-is the outer projecting portion of the ear. Also called pinna. ANS- Is the system of nerves that regulates body functions which have no direct voluntary control. Cerebrum- is the anterior and largest part of the brain‚ consisting of two halves or hemispheres and serving to control voluntary movements and coordinate

part and central core of the brain‚ beginning where the spinal cord swells as it enters the skull; the brainsteam is responsible for automatic survival functions. 8. Medulla- The base of the brainsteam; controls heartbeat and breathing. 9. Reticular Formation- A nerve network in the brainsteam that plays an important role in controlling arousal. 10.

Thalamus- The thalamus is the uppermost part of the brainstem. It directs information to the sensory cortex and provides feedback to the cerebellum and medulla. 3. Medulla- The foundation of the brainstem. It manages heartbeat and breathing. 4. Reticular formation- The nerve region travelling through the brainstem and thalamus. The network is responsible for governing arousal. 5. Cerebellum- The area located directly behind the brainstem. It processes sensory input‚ organizes movement‚ helps sustain

muscles cause the fibers’ calcium-binding capacity to decrease‚ which then limits muscle contraction‚ which causes muscle fatigue. (Mullick) During muscle fatigue‚ feedback of nerve impulses from the fatigued muscles interrupts on a part of the reticular formation and causes a hang-up of voluntary effort. (Amussen) It is important to understand that muscle fatigue results from metabolic reasons and not structural changes in your muscle. Peripheral muscle fatigue involves the motor units‚ such as motor

the dermis provides tensile strength and elasticity to the skin through its dermal fibres (collagen‚ reticular‚ and elastic fibres) that are embedded in an extrafibrillar matrix [72‚ 73]. The dermis is approximately 15 to 40 times thicker than the epidermis and can be further divided into a superficial part adjacent to the epidermis‚ the papillary dermis‚ and a deep thicker part‚ the reticular dermis. The papillary dermis interdigitates with the epidermis and is mostly composed of loosely arranged
