Answer:
Spermatogonia , Primary Spermatocyte, Secondary Spermatocyte, Spermatids and Spermatozoa.
Explanation:
Seminiferous tubules are the main site for spermiogenesis. The two main cells included in the seminiferous tubules are germ cells which produce sperms another one is the Sertoli cells which nurture the germ cells throughout the developement process.
There are 3different phases described below:
1. Proliferative Phase: Spermatogonia i the basal region of the tubular epithelium undergo mitosis. Spermatogonia divide to give rise to primary spermatocytes. All descendants of a B spermatogonium remain connected by cytoplasmic bridges, forming a syncytium - like cell clone which undergoes synchronous development.
2. Meiotic Phase:Each primary spermatocyte divides to give rise to two short-lived secondary spermatocytes, which in turn give rise to two spermatids each. The spermatids contain a haploid number of chromosomes (half the number of a somatic cell). Primary spermatocytes are the largest cells in the spermatogenic series and are located approximately midway within the seminiferous epithelium.The process of meiosis occurs over a long period, with prophase of the first meiotic division taking up to three weeks
3. Differentiation phase
This phase is also known as spermiogenesis.
Spermatids undergo transformation into spermatozoa. Many changes occur within the cells, the three major ones being:
i) formation of the acrosome, which covers the cranial part of the head. The acrosome will contain hydrolytic enzymes to allow fusion of sperm and egg for fertilisation.
ii) condensation of nuclear chromatin in the head to form a dark-staining structure
iii) growth of the tail opposite the acrosome, and loss of excess cytoplasmic material which is shed as a residual body. The body is phagoctosed by the Sertoli cells..
The left part of the maternal abdomen is the location where ultrasound transducer be placed to best auscultate fetal heart tones.

What is Right occiput posterior position?</h3>
This position involves the baby facing forward which is to the left of the mother's body.
The doppler ultrasound transducer should be placed on the left abdominal part of the mother to best detect the heart tones.

Josie stands doing active progressive muscle relaxation. once a group of her muscles exists contracted sufficiently, she should hold them in this state of tension for up to 8 seconds.
<h3>What is progressive muscle relaxation?</h3>
A non-pharmacological technique for deep muscle relaxation called progressive muscle relaxation is based on the idea that tension in the muscles is the body's psychological reaction to ideas that make one anxious, and that muscle relaxation reduces anxiety. All you require are concentration, focus, and a peaceful area where you won't be interrupted. The secret to using this technique is to contract each muscle group and hold the contraction for 5 seconds. You then exhale and wait 10 to 20 seconds for your muscles to completely relax before moving on to the next muscle group.
The creation of a sense of well-being, lowering blood pressure, and decreased muscle tension, which reduces the body's requirement for oxygen and lessens weariness and anxiety, are just a few advantages of progressive relaxation.
Hence, Josie stands doing active progressive muscle relaxation. once a group of her muscles exists contracted sufficiently, she should hold them in this state of tension for up to 8 seconds.

The correct answer is B. False
Explanation:
Integrative medicine refers to a holistic approach, in which multiple aspects of the patient's health are considered to provide adequate treatment or care. In this way, integrative medicine includes aspects such as emotional health, mental health, social health, etc. rather than only physical health.
Additionally, this approach has been proved to be effective, and due to this, modern academic medical centers in the U.S. and other countries promote its use, and in many medical centers, this is the approach implement. Moreover, integrative medicine is defined and allowed by law. Due to the previous ideas, it is false the use of integrative medicine is prohibited in most medical centers in the U.S.
Answer:
"The superiority of both forms of acupuncture suggests a common underlying mechanism that may act on pain generation, transmission of pain signals or processing of pain signals by the central nervous system and that is stronger than the action mechanism of conventional therapy," the authors conclude
