Gap junction

While it definitely slowed, the contractions were sporadic at best. The heart lost its regularity and showed random contraction intervals, some ranging shorter than normal while others had greater time gaps between contractions. Procedure 5: Effects of a Ligature on the Heart After the knot had been tied around the AV groove, no noticeable alterations were noticed to heart contraction. Upon tightening of the thread however, the heart appeared in clear distress. Beat irregularities ensued…

Mitchell, Smith, 2013, pg. 458). The action potential slowed down at the AV node, as the atria contracts. This happens right before exited to the AV bundle. The delay happens because of a small diameter of fibers that have very little amount of gap junctions (Marieb, Mitchell, Smith, 2013, pg. 458). AV Bundle, Bundle of His The only electrical connection between the atria and the ventricle. It allows the action potential to move from the interatrial septum to the interventricular septum,…

central nervous system. In this part, we shall cover the backward journey of transmission. Neurons transmit electrical information through the body. The process of transmission should flow well, but there exists a gap between one neuron and the next one called the synaptic junction. The gap is known as the synaptic cleft. Since the electrical signal cannot move over this cleft, it has to be converted into a chemical message called the neurotransmitter. The chemical message moves to the other…

extravasation on RUG. III Partial disruption Extravasation at the site of injury With visualized bladder. IV Complete disruption Extravasation at the site of injury Without visualized bladder (Less than 2 cm urethral gap). V Complete disruption Complete transaction with >2 cm urethral gap; Or extension into the prostate or vagina. Table 7: AAST Classification of urethral injury (Moore et al, 1992) A more recent classification for urethral injury was developed by the European Association …

Anatomy of cerebral cortex: Brain is most complex organ in human body. The ability of brain for its functioning normally is manifestation of various activities it takes participation in various activities of day to day life, being it hidden from the view or perceptible, like walking, smelling, thinking, laughing, speaking, and hearing. These manifestations are results of very coordinated and complex electrical and chemical activity within and between the cells those makes up our brain. Abnormal…

Important components of the neuromuscular junction where muscle innervation occurs include muscle and nerve fibres and motor end plates (Dhoot et al., 2013) whereas a neuron itself consists of a cell body or soma, axon, basal and apical dendrites (Megias et al., 2001). Neurons can be classified as…

Figure1.3: Band gap vs lattice constants diagram for hexagonal nitride compounds. The typical of measured band gap bowing for ternary alloys AlGaN and InGaN is shown by the solid line track[21]. 1.4. Unique Material properties of Gallium Nitride: The unique material properties of GaN engraves it as an prominent semiconductor material for many electronic and optoelectronic devices[18]. • The wide and direct energy band gap sorts GaN as an appropriate materials for device fabrication in the field…

The Achilles tendon is located at the back part of the heel. The tendon receives blood supply from three sources: the musculo-tendinous junction, the paratenon and distally at the tendon insertion to the bone. (Karlsson 2015) The Achilles joins the heel bone to your calf muscles, with its main purpose is plantar flexion, which is the bending of the foot downwards at the ankle. The average age of a person suffering this injury is twenty-nine to forty with a large majority of all patients being…

data, methods, and theory for the past investigation at the West Berkeley Shellmound and use critical evaluations to construct an alternative research design for the site in the question. Background The West Berkeley Shellmound is located at the junction of Second Street and Hearst Avenue in Berkeley, California. The mounds original dimensions could not be accurately determined because most of it had been removed prior to excavation. It was believed to cover an elliptical area, approximately…
