To identify:
The muscles of the anterior right hip and thigh in the figure.
Introduction:
Around 640 skeletal muscles are present in a typical human body that is non-striated. It has voluntary control of the somatic nervous system. It provides erectness and movement to the body.

Explanation of Solution
Pictorial Representation: Figure 1 represents the anterior right hip and thigh muscles.
Figure 1: Anterior right hip and thigh muscles
The anterior right hip and thigh muscles help in the movement of the leg. The different muscles are as follows: -
- Tensor fasciae latae: - It is a muscle of the thigh. It helps in maintaining balance to the pelvis during running, walking, and standing.
- Sartorius: - It is the longest muscle of the body that runs through the thigh. It provides flexibility and rotation at the hip and the knee joint.
- Rectus femoris: - It starts from the ilium and runs straight down the leg. It is connected to the patella and only muscle to pass the knee and the hip joint.
- Vastus lateralis: - It starts from the greater trochanter and lateral lip of linea aspera. It stretches the knee joint and provides stability to the patella.
- Vastus medialis: - It starts from the intertrochanter and medial lip of the linea aspera. It also stretches the knee joint and provides stability to the patella as its fibers are present at the end part.
- Psoas major: - It starts from the lumbar vertebrae and joins with the Iliacus muscle to form iliopsoas muscle. It provides flexibility to the thigh at the hip joint.
- Iliacus: - It starts from the iliac fossa of the pelvis and joins with psoas major to form iliopsoas muscle. It also provides flexibility to the thigh at the hip point.
- Adductor longus: - It is originated from the pubic body and forms the femoral triangle. It adducts the thigh at the center.
- Gracilis: - It is situated in the groin and starts at the pubic bone and ends at the upper medial. It adducts the hip flexes the knee.
Thus, the muscles of the anterior right hip and thigh are present for the movement of the leg through the hip joint and the knee joint. It provides flexibility to thighs.

- What is this?arrow_forwardMolecular Biology A-C components of the question are corresponding to attached image labeled 1. D component of the question is corresponding to attached image labeled 2. For a eukaryotic mRNA, the sequences is as follows where AUGrepresents the start codon, the yellow is the Kozak sequence and (XXX) just represents any codonfor an amino acid (no stop codons here). G-cap and polyA tail are not shown A. How long is the peptide produced?B. What is the function (a sentence) of the UAA highlighted in blue?C. If the sequence highlighted in blue were changed from UAA to UAG, how would that affecttranslation? D. (1) The sequence highlighted in yellow above is moved to a new position indicated below. Howwould that affect translation? (2) How long would be the protein produced from this new mRNA?

- Molecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold. The ( ) indicate the reading frames in the exons; the included intron 2 sequences are in bold. A. Would you expected this change to be harmful? ExplainB. If you were to do gene therapy to fix this problem, briefly explain what type of gene therapy youwould use to correct this. Please help. Thank youarrow_forwardMolecular Biology Question Please help.
