prepare a four minute summary explaining how chemical signals from the endocrine system drive development of the reproductive system in both sexes. Your summary should include a comparison of this process among males and females. Your summary should be well organized, and should make sense to somebody who doesn’t have the guiding questions in front of them.

In your summary you should address the following questions:

• What hormones are involved in this process?
• What cells do these hormones interact with?
• What effect do the identified hormones have?
• What additional actions might these hormones have within the body (apart from the reproductive system)?

T/F

1. Specific sequences in the mRNA directly effect the sorting of proteins into various organelles in the cell. T/F?

2. All mitochondria proteins are coded for & synthesized in mitochondrial matrix. T/F?

3. All protein folding occurs spontaneously without the need of energy. T/F?

Read the following Case Study and answer the questions based on the information.

History of Present Illness: The patient has been noted to have some bright, red bleeding intermittently for approximately 8 months, initially presumable of a hemorrhoidal basis. She recently has had intensification of the rectal bleeding but no weight loss, anorexia, or obstructive pain. No significant diarrhea or constipation. Some low back pain, probably unrelated. Recent colonoscopy by Dr. Scoma revealed a large sessile (attached by a broad base) polyp, which was partially excised at the 20 cm level, showing infiltrating adenocarcinoma at the base.

Benzodiazepines are positive allosteric modulators at the GABA-A receptor. a) Describe how positive allosteric modulators affect receptor function. b) Discuss the mechanism of action of benzodiazepines and their effect on central nervous system (CNS) activity. c) GABA is also an agonist at GABA-B receptors, which are G protein coupled receptors that couple to Gi. Explain the signalling pathways that will be activated when GABA binds to the GABA-B receptor.

1. List as many features as you can that facilitate the mobility of the glenohumeral joint. Think about the shape of the capsule, shape of the joint surfaces, ligaments, structures around the joint, accessory joints, and bones that contribute to full range of movement around the shoulder. Consider how these affect the mobility of the shoulder joint and shoulder complex, and how they may be a tradeoff for loss of stability.

Factors increasing mobility of the joint:

- Bones:

- Capsule:

- Synovial membrane & bursae:

- Muscles:

- Accessory joints:

- Scapulo-humoral rhythm:

Factors maintaining stability of the joint:

- Labrum:

- Rotator cuff:

- Ligaments:

- Tendons:

When you talk about each factor, please focus on its role in either mobility and stability. For example, you don't have to describe the attachment of the capsule and the ligaments, but what is specific in the capsule to increase mobility, and how each ligament supports and stabilizes the joint. Another example about the rotator cuff muscles, you don't have to describe each muscle in detail, but how they are the most important factor in maintaining the stability of the joint.

Explain how a qualitative anatomical analysis can be applied to improve training technique. Why would a clinician or practitioner want to do this and how could it help?
