Biology Chapter 46 Homework Xitlali Sedano P.3 4/12/12 Biology Muscle Tissue Is composed of cells that contract Every function that muscle tissue performs- from creating a facial expression to keeping the eye in focus- is carried out by groups of muscle cells that contract in a coordinate fashion There are three types of muscle tissues Skeletal Muscle Moves the bones in your trunk, limbs and face Smooth Muscle Handles body functions that you cannot control consciously such as the movement of food through your digestive system Cardiac Muscle Is found in your heart It pumps blood through your muscles Nervous Tissues Contains cells that receive and transmit messages in the form of electrical impulses Makes up the human brain, spinal cord and nerves

Axon

Action potential

Synapse

Tags:

Biological Psychology – Focuses on links between biology and behavior. Neuron – A nerve cell Dendrite – Branching extension, receives messages Axon – Extension of a neuron, sends messages Myelin Sheath – Helps protect and insulate Action potential – A neural impulse, electrical charge that travels down the axon. Threshold – the level of stimulation required to trigger a neural impulse. Synapse – The junction between the axon tip (send) and the dendrite (receive) Neurotransmitters – Chemical messengers that traverse the synaptic gaps between neurons. Acetylcholine – Triggers muscle contractions Endorphins – “Natural morphine”, Pain control and pleasure. Nervous system – Electrochemical communication system of the body

Pons

Health

Major Structures of the Brain Structure Description Major Functions Brainstem Stemlike portion of the brain, continuous with diencephalon above and spinal cord below. Composed of midbrain, pons, medulla oblangata. Relays messages between spinal cord and brain, from brainstem cranial nerves to cerebrum. Helps control heart rate, breathing rate, blood pressure. Involved with hearing, taste, other senses. Cerebellum Second largest part of the brain. Located behind pons, in posterior section of cranial cavity. Composed of cerebral cortex, two lateral lobes, central flocculonodular lobes, medial vermis, some deep nuclei. Process center involved with coordination of muscular movements, balance, precision, timing, body positions.

Neuron

The Neural Impulse: Using Energy to Send Information pg75 • Neuron At Rest -The Neuron at rest is a small battery, from the uneven Ion charges from the fluid around it of Sodium (Na) and Potassium (K). -Resting Potential – The Stable, Negative Charge when the Cell is inactive. •The Action Potential - Action Potential – A very brief shift in a Neuron’s electrical charge that travels along an axon. -Absolute Refractory Period – Minimum length of time after an action potential during which another action potential cannot begin. Only about 1 or 2 Milliseconds. -All-Or-None Law – Neural Impulses either Fire or don’t fire. There is no Half-Fire. A faster Rate of transmission means a stronger Stimulus. •The Synapse
