PAL: Cadaver > Muscular System: Upper Limb > Lab Practical > Question 4

Identify the highlighted muscle.

Answers

Answer:

Brachialis

Explanation:

The Brachialis is an anterior skeletal arm muscle that extends from the medial arm to the superior area of the forearm. The brachialis fibers originate in the anterior part of the humerus and direct to the inferior part of the elbow, where they insert in the upper region of the ulna and distal radius. This muscle is an elbow flexor being used in every movement needed to approximate the anterior part of the forearm to the arm. It is a very thick and powerful muscle that acts with high speed.  

The upper limb or arm is the functional unit of the human body, which is made up of 6 different muscular regions, such as the pectoral, upper arm, hand, posterior forearm, and anterior forearm.

In the given image of the upper extremity, the muscle highlighted is the brachialis.

Brachialis anticus or the Teichmann's muscle is present in the upper extremity, which helps in the flexion of the elbow. The muscle is situated in the deeper biceps brachii and makes up the floor region of the elbow pit.

The muscle originates in the anterior part of the humerus and directs the inferior of the elbow. The brachialis muscle is one of the largest flexors of the elbow, which provides the movement or flexion of the forearm at the elbow.

Therefore, the given image is of the brachialis muscle.

Why is DNA replication significant for maintaining genetic stability

Answers

The information stored in the DNA is essential for life. If a cell dies the body must replace that cell. The only way to replace the cells is to first copy the information that the cell contained. There is a complex system of proteins and enzymes that unravel the DNA double helix so that the DNA can be copied.

Meaning of invertebrate and vertebrate​

Answers

Answer:

Vertebrate:spine Invertebrate:no spine

Explanation:

Answer:

Invertebrates are animals that do not have backbones. 95%-97% of the members of the animal kingdom are invertebrates such as sponges, jellyfishes, squids, and roundworms.

Vertebrates, on the other hand, are animals with a backbone or a vertebral column and are composed of six groups: mammals, birds, reptiles, amphibians, and fishes. Humans are members of the vertebrates family too but are sometimes exempted from the list when the discussion leans towards animals.

Answers

Answer:

diffusion through a selectively permeable membrane

Explanation:

The cell membrane selectively allows certain substances to enter or leave a cell . This implies that cell membranes are selectively permeable; they allow some substances to pass through, but not others.

Direct transport of materials across the cell membrane is often passive. Passive transport does not require energy to occur. Passive transport is the movement of substances  from a region of higher concentration to a region of lower concentration. A concentration gradient is always required.

The diffusion through a selectively permeable membrane is an example of passive transport.

The iodine moves into the dialysis tube across the semi permeable cell membrane from a region of higher concentration to a region of lower concentration in response to a concentration gradient.

Suppose that a rabbit breeder notices two individuals in a litter with large, round noses and names this trait the clown trait. He obtains another rabbit that has a long, thin nose and names it the Pinocchio trait. After breeding the rabbits with unusual nose shapes to wildâtype individuals for several generations, he decides to cross rabbits from families with a history of the clown and Pinocchio traits. The first litter from this cross results in individuals of four phenotypes. The phenotypes are clown, Pinocchio, wildâtype, and heartâshaped noses. The pedigree illustrates the inheritance of these traits. Individuals 1 and 4 are siblings and are known to come from a true-breeding wild type line.

1. What is the most likely mode of inheritance for the clown nose?

a. -linked
b. X-linked dominant
c. X-linked recessive
d. Autosomal dominant
e. Autosomal recessive

2. What is the most likely mode of inheritance for the Pinocchio nose?

1. Sex-influence
2. X-linked dominant
3. X-linked recessive

How do the different diets of organisms affect their eating patterns?

Answers

Answer:The evolutionary history of hominins has been characterized by significant dietary changes, which include the introduction of meat eating, cooking, and the changes associated with plant and animal domestication. Decades of anthropological research have been devoted to elucidating this dietary history, in part because these shifts were likely associated with major anatomical and cultural changes (e.g., the increase in relative brain size and the advent of modern civilization via agriculture). However, this reconstruction is also crucial for understanding the evolutionary context of our modern diets and the diseases often associated with them.

In parallel with the historical reconstruction of hominin diets, molecular evolutionary analyses have been used to interrogate the genome for signals of genetic adaptations to different dietary regimes. A major advantage of many evolutionary genetic approaches is that they do not necessarily require strong assumptions about the specific genes and alleles that were targets of diet-related selective pressures. For this reason, evolutionary genetic analyses have the potential not only to inform existing adaptive hypotheses of hominin dietary history, but also to help generate new ones.

Here, we bring together these two areas of inquiry, namely anthropology and evolutionary genetics, to highlight their recent findings related to human dietary history and to discuss the limitations of different approaches. We start by providing a brief overview of the major dietary shifts in hominin evolution and discussing the evolutionary genetics methods and approaches used to identify signals of natural selection. We then review the results of genetic studies aimed at detecting the loci that played a major role in dietary adaptations and conclude by outlining the potential of future studies in this area.
