Human Anatomy Quizzes Online & Trivia

The great toe is medial to the little toe. In Latin, Hallux is used to refer to the big toe. There are five toes on each human foot. Each toe consists of three phalanx, and there are joints between each phalanx which are called interphalangeal joints. The proximal phalanx bore of toe articulates with the metatarsal bone of the foot. The first toe is also known as the innermost toe. The hallux is flexed by the flexor hallucis longus muscle, which is located in the deep posterior of the lower leg. Both the hallux and the little toe have unique muscles.

The transverse plane is the plane that divides a body into superior and inferior portions. From a 3-dimensional point of view, the transverse plane usually coincides with the x-axis of the 3d space. It is directly perpendicular to the sagittal plane and coronal plane.

The axial plane or also known as the transverse plane is the line that runs perpendicular to your body’s frontal reference planes. The axial runs horizontally with the floor while the frontal reference planes run vertically to your body when in a standing position. The axial plane divides the body into cranial and caudal portions or head and tail, while the two sagittal reference planes (dividing the left and right sides of the body) and the coronal plane which divides the front and the back portions. All these planes are used to describe motion and are very helpful with medical imaging for CT, MRI, and PET scans. They are like anatomical landmarks.

1. rectouterine pouch-The rectouterine and vesicouterine pouches are the two pouches created by draping the peritoneum over the pelvic organs. these pouches are the two lowest extents of the peritoneal cavity, so to answer this question, you just need to decide which one goes lower. since the uterus is folded over the bladder, the rectouterine pouch can extend to a slightly lower level than the vesicouterine pouch, which makes c the correct answer. the pararectal fossa is formed by lateral reflections of perineum over the superior one-third of the rectum; this space gives the rectum room to fill with feces. the paravesicular fossa is a space near the bladder that allows the bladder to expand. why is the rectovesicular pouch incorrect? it's only found in males, not females! (but, if the question had asked about males, the rectovesicular pouch would have been the correct answer.)

The answer to this question is E. The cranial cavity contains the brain. It is not only the brain that is inside the cranial cavity. It may also include other organs that the rest of the body needs to survive. The cranial cavity is also lined with cerebrospinal fluids. This can be very effective in cushioning blows to the head. This explains why people’s heads are durable provided that the force is not stronger than the head. Aside from the cranial cavity, there are three other body cavities that all protect essential organs of the body. The other holes are the thoracic cavity, abdominal cavity, and the pelvic cavity.

The relationship between the big toe and the little toe is medial, or lateral, depending on which way you’re going down the foot. From the little toe to the big toe, it’s medial; the other way around, it’s lateral. That’s really all it is, and there’s a good reason for that. The word “medial” comes from a Latin term that means “middle”. So if something is medial, it’s somewhere in the middle of an arrangement. “Lateral”, on the other hand, is to the side. Often, it means to the left in relation to the middle, but it could also mean that this item is to the right, depending on the context. That’s the relationship between the big toe and the little toe in a nutshell.

Deep inguinal lymph node(s)-the femoral canal usually contains a deep inguinal lymph node, called the gland or node of cloquet. this canal opens to the abdominal cavity through the femoral ring, so it might be the site of a femoral hernia. the femoral artery and vein are enclosed in the femoral sheath with the femoral canal, but they are not in the femoral canal. the femoral nerve is also in the femoral triangle, but it is not enclosed by the femoral sheath. it is the most lateral structure in the femoral triangle. the ilioinguinal nerve is not really part of the anatomy of this region. it innervates muscles of the lower abdominal wall and is associated with the superficial inguinal ring. make sure to remember the difference between the femoral canal and femoral sheath

Myometrium-this question is phrased in a slightly tricky way, so it's important to break it down before looking at the answers. There are two things to think about here. First, you need to decide if a structure is part of the uterus. If it is part of the uterus, then you need to decide if it is shed during menstruation. The correct answer will be a structure that is part of the uterus but is not shed during menstruation. Answers about structures that are not shed during menstruation because they are not part of the uterine wall are incorrect. The myometrium is our correct answer. It is the middle muscular component of the uterine wall and it is not shed during menstruation. The endometrium is the inner mucosal coat of the uterus. It exhibits many characteristic changes during the menstrual cycle and all but its stratum basalis is shed during menstruation. The mesometrium is the mesentery of the uterus which forms the major part of the broad ligament of the uterus. It is not even part of the uterine wall, so it's not the answer to look for. Cervical mucosa lines the cervix, which is the inferior portion of the uterus. This mucosa is shed during menstruation. Finally, the uterus does not have rugae - rugae are the folds found in the lining of the vagina (and stomach).

1. None of the above

Isn't the small intestines responsible for absorption as well?

The foot is inferior to the knee

1. ampulla of the uterine tube-fertilization normally takes place in the ampulla of the uterine tube. this is the middle segment of the uterine tube, and it is the longest and widest segment. the infundibulum is the funnel-shaped distal end of the uterine tube, and the isthmus is the narrowest part of the uterine tube which connects directly to the uterus. the uterine lumen is the site of implantation, not fertilization. finally, the cervical canal is the pathway out of the uterus at its inferior end- it would not be an appropriate site for fertilization or implantation.
