Premium Muscle contraction Acetylcholine Neuromuscular junction
Neuronal signaling in muscle contraction is triggered when an action potential reaches the neuromuscular junction. At this junction‚ acetylcholine (ACh) is the main neurotransmitter. Packaged in vesicles‚ ACh fuses with the neuron’s membrane and is released into the synaptic cleft. ACh diffuses toward the motor end plate and bind to the neurotransmitter receptor on it. The muscle fiber is then triggered to produce an action potential of its own that spreads through the muscle’s T-tubules. The sarcoplasmic

What is psychology? The scientific study of behaviour and the physiological and mental processes that underlie such behaviour. A profession that applies the findings of psychological research to real world problems Wilhelm Wundt First psychology lab in 1879 Main focus was on consciousness Many students established research labs in North America and Germany.

Elements 1 Neurons: The Basic Elements of Behavior Introduction to Psychology 101 Elements 2 The Basic Elements of Behavior The human body is a tremendous creation that is quite capable of performing a multitude of multifaceted movements and thoughts. In addition to its’ ability to move and think‚ the human body also allows numerous senses to become involved throughout ones daily routine. A person’s ability to think‚ remember‚ and experience emotion are all results of the body’s

occur. At the start my lab partner was calm resulting in the blood pressure to be around 125/59 with 55 beats per minute. The second time we did it‚ the numbers were fairly similar 126/59 and 62 beats per minute. At the beginning there is no action potential occurring or the pacemaker is not racing to make the heart beat quicker because the body is not using much energy since it is basically at a resting state. You can detect the heart beats by using the QRS EKG method where each one can represent

BIOLOGY SYNOPTIC ESSAY – UNIT 5 – JUNE 13 THE MEMBRANES OF DIFFERENT TYPES OF CELLS ARE INVOLVED IN MANY DIFFERENT FUNCTIONS – 25 MARKS Membranes are found in all organisms‚ around and within cells. They control the movements in and out of cells‚ as well as protecting cells. They also allow different functions to occur. They have the same basic structure called the plasma membrane. All plasma membranes‚ around or inside cells have a same phospholipid bilayer structure. Phospholipids contribute to

A. Tonic Spiking Most neurons are excitable‚ that is‚ they are quiescent but can fire spikes when stimulated. To test this property‚ neurophysiologists inject pulses of dc current via an electrode attached to the neuron and record its membrane potential. The input current and the neuronal response are usually plotted one beneath the other‚ as inFig.1(a).Whiletheinputison‚theneuroncontinuestofireatrain of spikes. This kind of behavior‚ called tonic spiking‚ can be observed in the three types of cortical
