The female ovarian cycle is divided into two stages. What are they called and what is occurring during each stage?

A neuron has three main parts: dendrites, cell body, and axon. A neuron may send signals to other neuron or other tissues (effectors). Describe the physiology of how the signal moves from one point to the other and the other organ or tissue responds.

In 2-3 sentences describe how SSRI drugs function as antidepressants. Your description should (i) describe whether SSRI drugs function as agonists or antagonists, (ii) specify which neurotransmitter pathway they act on, and (iii) how the SSRI mechanism of action treats clinical depression with respect to affecting neurotransmitter levels

Compare oral, sublingual, and rectal administration routes of drugs providing their advantages and disadvantages. Giving examples explain how the bioavailability of drugs would be affected by these administration routes.

1. Describe the Kirby-Bauer test and how it is used to determine antimicrobial sensitivity

Why are sympathetic ganglia near the spinal cord while parasympathetic ganglia are near the target organ? I'm trying to reason this out so I can memorize less. If there's no explanation, is there a mnemonic that you use?

According to the Anxiety and Depression Association of America, over 20% of Americans are diagnosed with anxiety and/or depression (2018). As we learn about the nervous system this module, we can use these two common disorders to help gain an understanding of basic nerve function.

For your discussion post, choose either depression or anxiety and answer the following questions. Remember to use your own words when explaining these concepts.

• How does depression/anxiety affect neurotransmitters?
• How does depression/anxiety affect synapses?
• How does depression/anxiety affect neuron function?

In your reply posts, share how various treatments may improve the physiology of the disorders discussed. Since these are common disorders, you may choose to share personal experiences. If so, keep the information you share confidential and do not share names or identifying information of others.

Anissa is working in an electrophysiology lab. She has isolated an excitable patch of membrane in the cell, generates one action potential but then finds that she cannot generate any action potentials, even with the supre-threshold stimulation. Which of the following statements could most likely account for this scenario?

a) The cell Anissa is recording does not contain voltage gated Na+ channels
b) The intracellular concentration of K+ ions is now higher than the extracellular concentration

c) The membrane contains voltage gated K+ channels that produce after-hyperpolarizations
d) The voltage gated Na+ channels in the membrane are all permanently inactivated

Explain the mechanism of transport of oxygen by blood. And explain the mechanism of transport of carbon dioxide by bood

What type of movement occurs at the following JOINTS during the (1)stance phase, (2) preparatory phase, (3)movement phase, and (4)follow-through phase of a soccer kick?

JOINTS: Cervical, Lumbar, Shoulder Girdle, Shoulder Joint, Elbow, Radioulnar, Wrist, Fingers, Hip, Knee, Ankle/Subtalar, Toes

What contractions occur in each movement? (isometric, concentric, or eccentric)

1. which cells are responsible for blood clotting? name the 3 major steps of blood clotting.

Mary went on a run at the park to get her mind off her busy week. When she went on her run she saw a huge bear. She was in shock and froze, feeling her muscles starting to constrict and finding herself having trouble breathing. When the bear started coming after her she panicked and ran for her life.

1. Which of the following are true of her autonomic nervous system?

A. Mary’s muscles were being innervated by the cranial and sacral region of her sympathetic nervous system.

B. Mary’s ventricle columns of her periaqueductal gray caused her immobility.

C. Cortisol and adrenaline were being released and spread through her body causing the excitation of her muscles and inhibition of her bronchioles.

D. Two are correct.

E. All are correct.

2. As Mary ran away she luckily lost the bear but she ran so fast that she tripped over a log of wood hitting her knee pretty hard and screaming “OUCH.” Which of the following correctly explain her efferent pathways which are taking the information back from her Central Nervous System to her motor neurons?

A. Her somatic motor neurons consist of several neural pathways from the Central Nervous System to innervate the skeletal muscle.

B. Her motor neurons consist of adrenergic receptors on its dendrites/ cell bodies which bind to neurotransmitters, adrenaline or noradrenaline

C. No more than ten of her muscle fibers are innervated per motor neuron.

D. All of the above.

E. None of the above.

3. As Mary was on her way home she decided to go to the doctor to make sure she didn’t get an infection from her fall. When she got there the doctor first took her vitals. He told her everything was fine with her leg but when he used a stethoscope to listen to her heartbeat he heard a lub-dub-whistle. Which of the following are correct?

A. Scar tissue has built up in her atrioventricular valve which makes opening of the valve harder.

B. The murmurs of the heart occurs during systole as the heart is ejecting blood during contraction.

C. The blood is moving by what's called turbulent flow.

D. Two are correct.

E. All are correct.

A. For the lateral ventricles, write 2-3 sentences describing:

(i) its location in the brain

(ii) its neurological relationship to nearby structures

(iii) any neurologic disorders associated with its dysfunction.
