What is the resting membrane potential and why is it important? Describe 2 ways the cell maintains the resting membrane potential.

A patient in the hospital appears disoriented and is complaining of severe diarrhoea. What do you think is working with this patient? How he will the patient's body attempt to compensate for this problem? (answer this from an acid/base perspective, do not assume symptoms that are not mentioned in the question)

what is the anatomcal location of major organs in the cardiovascular and lymphatic systems?

Which of the following is NOT true regarding epithelial tissue? (more than one option maybe chosen)

a. Epithelial tissue is avascular, and must exchange waste and nutrients through diffusion with neighboring tissue.

b. Epithelial tissue can be characterized as squamous, cuboidal, columnar, or transitional.

c. Epithelial tissue characteristics are determined by the ratio of ground substance to fiber volume, as well as the type of matrix.

d. Epithelial tissue can be defined by the number of cell layers, being simple, stratified, or pseudostratified.

Hello, please answer and explain the following questions and topics regarding cell and tissue characteristics

1) Predict the effects of dysfunction in each cellular organelle

2) Differentiate the four functions of the cell membrane

3) Predict how changes in oxygen delivery to cell change cellular respiration and levels of adenosine triphosphate and carbon dioxide.

4) Predict changes in membrane potentials based on diffusion of ions

5) Link the process of cell differentiation to the development of organ systems in the embryo and the regeneration of tissues in postnatal life.

Ryan is finishing his trail half marathon and starts to sprint the last half mile of the race. During this time Ryan’s legs really start to become sore. Describe, in detail, what is happening metabolically in his muscles during this last half mile. Elaborate on how this affects the rest of the metabolic pathways.

Bower is a 3-year –old male English Pointer who presented with weakness and difficulty rising. He also recently developed a very red and sore area across the top of his nose. Bover had a slight fever, significant muscle atrophy, enlarged peripheral lymph nodes and an erythematous lesion on the dorsum of his nose.

He had an increased plasma protein concentration (8.0 g/dL), a high white blood cell count (18 X 10³ /ul), high numbers of neutrophils within joint fluids (no microorganisms cultured) consistent with immune-mediate inflammation. An antinuclear antibody (ANA) test was performed with a titer of 640 (positive is greater than 100). Antigen-antibody complexes (anti-C3 and anti-IgG) were also observed at the dermal-epidermal junctions of Bower’s nasal lesion.

Compare and contrast the auditory and gustatory pathways. Start with explaining how stimuli are molecularly detected by the receptor cells and how the membrane potentials are depolarized. Discuss what triggers the action potentials of the sensory neurons and state which cranial nerves relay the action potential to the brainstem. Name the first nuclei in the brainstem (name the region of the brainstem) that form synapses with the central sensory neurons. Trace the rest of the pathways to the primary sensory cortex where the awareness of the special sensory stimuli occurs (name the lobe of the brain).

Which of the following statements does not describe the classical activation pathway of complement?

A) Initiation of the classical pathway of the complement system requires formation of an antibody antigen complex.

B) The classical pathway results in complement activation of the inflammatory response only.

C) The classical pathway converges with the alternative pathway, resulting in the same possible complement-mediated immune responses.

D) The classical pathway is an example of an adaptive immune response.
