How to determine if the skeleton is male or female?

Question 1 

During muscle contraction, Sarcomeres shorten via an elaborate mechanism involving acting and myosin filaments. 

Question 2 

Chemicals that serve as signals that elicit a response from target cells are called transmitters. 

Question 3 

How many bones are in the human body? 206 bones 

Question 4 

Which bacterial STD can be treated with antibiotics if caught early? Symptoms are infectious sores on the vagina, penis, anus, lips, and mouth. Syphilis. 

Question 5 

According to the course textbook, which of the following birth control methods has the lowest rate of unintended pregnancy? Implantables. 

Question 6 

Match each gland to its function. 

Thyroid: C. Secretes calcitonin to lower blood calcium levels. 

Parathyroid: F. Secretes a hormone that raises calcium levels. 

Hypothalamus: E. Secretes a gonadotropin-releasing hormone. 

Adrenal Gland: B. Secretes both testosterone and estrogen. 

Pancreas: A. Secretes insulin and glucagon to regulate glucose levels. 

Question 7 

Match each part of the cerebrum or cerebellum stem to its association or function. 

Parietal Lobe: F. Processes voluntary muscle movement, involved in memory 

Frontal Lobe: K. Generating and understanding speech and other sensory information 

Temporal Lobe: G. Involved in processing auditory and olfactory information 

Occipital Lobe: D. Processes visual information 

Cerebral Cortex: J. Generating and understanding speech and other sensory information. 

Thalamus: H. Processes information about touch and self-awareness 

Hypothalamus: A. Control center for hunger, thirst, and body temperature. 

Cerebellum: E. Controls balance, muscle movement, and coordination 

Brain Stem: I. Responsible for autonomic (involuntary) functions 

Question 8 

Also known as nerve impulse, a brief reversal of the electrical charge across the membrane of a nerve cell is known as Action Potential . 

Question 9 

The presence of size and body composition accounts for the differences in muscle mass among male and female humans. 

Question 10 

Bacterial STDs are usually treated with antibiotics , which is not an effective treatment for viral STDs. 

Question 11 

Antagonistic muscle pairs contract in opposition to one another to create the movement of limbs and appendages. 

Question 12 

Imagine that you are a forensic detective and you have been tasked with analyzing a complete skeleton. How might you go about determining if the skeleton is male or female? What characteristics would you look for? 

There are various differences between the male and female skeletons. The most essential difference is in the pelvis of the skeleton. The female pelvis tends to be wider and lower than that of the male. Pointedly, both the sacrum and the pelvic ring of the female skeleton should be wider and more circular compared to that of a male skeleton to facilitate new-born’s passage. Besides, the acetabula of a female skeleton are further apart and there is a decreased distance between the greater trochanters alongside the width of the hips. Secondly, I would examine the mass and thickness of the and mass of the skull. Notably, the male skulls are usually thicker and heavier than the female skulls. Secondly, the thoracic cage of a female skeleton would be more rounded and smaller than that in a male skeleton. The other characteristic is in the wideness of the skeletal shoulder. In male skeletons. The shoulders would be wider than that of the female because of the larger muscular development. Another characteristic I would examine in the skeleton to determine whether it is a female or male one is the lumbar curve. In a female’s skeleton, the lumbar curve would be greater and the pelvis would be tilted anteriorly, making it appear sway-backed. 

Question 13 

Discuss the difference between general senses and special senses. Then, of the special senses, decide which you think is either most important or least important and explain your position. 

The human body contains two primary types of senses named the general and the special senses. These two types of senses differ significantly. Some of the primary difference between the general senses and specialized senses is that the general senses are both simple in structure and scattered throughout the body. Notably, all the general senses tend to be associated with the sense of touch. Instead of the special organs such as those in special senses, the general senses have sensory information regarding touch gathered by the skin and other tissues of the body, which are organs playing other essential roles other than gathering sense information On the flip side, the specialized senses receive particular senses such as smelling, tasting, hearing, as well as the equilibrium. The specialized senses are different from the general senses since they are anatomically from each other. Furthermore, they are also concentrated in various locations that are specific in the head. Moreover, the specialized senses are different from the general senses such that they tend to be embedded in the epithelial tissues that are essentially within the various complex sensory organs such as the ears and the eyes. Additionally, the special senses’ neural pathways also marks another difference from the general senses since they more complex compared to the ones in general senses.
