Clic Cosmetology: Anatomy And Physiology (Part 2)

It is composed of 206 bones that vary in size and shape and are connected by movable and immovable joints. Except for the tissue that forms that major part of the teeth, bone is the hardest tissue in the body. It is composed of connective tissue consisting of about one-third animal matter, such as cells and blood, and two-thirds mineral matter, mainly calcium carbonate and calcium phosphate.

There are two types of joints: movable, such as elbows, knees, and hips; and immovable, such as the pelvis or skull, which allows little or no movement.

The mandible is the lower jawbone, which is the largest and strongest bone of the face.

The occipital bone is the correct answer because it is the hindmost bone of the skull, located below the parietal bones. It forms the back of the skull above the nape.

Two temporal bones form the sides of the head in the ear region.

The phalanges are the bones in the fingers and toes. In this case, the question is specifically asking about the bones in the arms and hands, so the correct answer is the phalanges. The other options listed (radius, ulna, carpus, metacarpus) are all bones in the forearm and wrist, not in the fingers.

The frontal bone is one of the bones of the cranium and it forms the forehead. It is located at the front of the skull and extends from the top of the head down to the eyebrows. The frontal bone also forms part of the roof of the eye sockets and contributes to the shape and structure of the face.

The correct answer is "Radius" because it is the smaller bone in the forearm on the same side as the thumb. The radius is located on the lateral side of the forearm, while the ulna is on the medial side. The radius plays a crucial role in the movement of the forearm and hand, allowing for rotation and flexibility.

Two zygomatic or malar bones are what form the prominence of the cheeks.

The clavicle is the correct answer because it is the bone that joins the sternum (breastbone) and scapula (shoulder blade). It is commonly known as the collarbone and is located in the chest, shoulder, and back region. The other options listed, such as ribs, scapula, sternum, and thorax, are all related to the chest and shoulder area, but only the clavicle specifically fits the description of a bone that connects the sternum and scapula.

The correct answer is "Metacarpus" because it refers to the parts of the hand that contain five bones between the carpus (wrist) and phalanges (fingers). The metacarpus consists of the five long bones that make up the palm of the hand, connecting the wrist to the base of each finger. It is an important part of the hand's skeletal structure and provides support and flexibility for gripping and manipulating objects.

The cranium is made up of eight bones.

The correct answer is Ribs because they are one of the twelve pairs of bones that form the wall of the thorax. The thorax is the chest region, and the ribs play a crucial role in protecting the organs within the thoracic cavity, such as the heart and lungs.

The cervical vertebrae is the seven bones of the top part of the vertebral column located in the neck region.

The hyoid bone is the U-shaped bone at the base of the tongue that supports the tongue and it's muscles; also called "Adam's apple."

Osteology is the correct answer because it specifically refers to the study of the anatomy, structure, and function of bones. This field of science focuses solely on bones, whereas anatomy and physiology encompass a broader range of topics related to the human body. Histology, on the other hand, is the study of the microscopic structure of tissues, which is not directly related to bones.

Two nasal bones form the bridge of the nose.

The sternum is the correct answer because it is a flat bone that forms the ventral support of the ribs. It is also known as the breastbone and is located in the chest, shoulder, and back region. The scapula, thorax, clavicle, and ribs are also bones in this region, but they do not specifically form the ventral support of the ribs like the sternum does.

The ulna is the correct answer because it is the inner and larger bone of the forearm. It is attached to the wrist and located on the side of the little finger. The humerus is the bone in the upper arm, the radius is the other bone in the forearm, carpus refers to the bones of the wrist, and phalanges are the bones in the fingers.

The humerus is the correct answer because it is the uppermost and largest bone of the arm, extending from the elbow to the shoulder. The ulna and radius are bones of the forearm, while the carpus and phalanges are bones of the hand. Therefore, the humerus is the most appropriate answer based on the given description.

Two parietal bones form the sides and crown of the cranium.

The sphenoid bone is considered the key bone of the skull because it is located in the middle of the skull and forms a central base for other cranial bones to attach to. It is a complex bone that helps support the structure of the skull and also plays a role in protecting important structures such as the brain and the optic nerves. Additionally, the sphenoid bone contains several important foramina (openings) that allow for the passage of blood vessels and nerves.

The bone of the cranium located between the eyes is called the ethmoid bone. It is a delicate, cube-shaped bone that forms part of the nasal cavity and the eye sockets. The ethmoid bone is situated in the front of the skull, between the frontal bone (which forms the forehead) and the sphenoid bone (which is located behind the eyes). It is responsible for separating the nasal cavity from the brain, and also contains small air-filled spaces called ethmoid sinuses.

Two small, thin lacrimal bones are located at the front inner wall of the orbits.

Two maxillae are the bones of the upper jaw. (singular: maxilla)

The scapula is the correct answer because it is one of the bones of the chest, shoulder, and back. It is commonly known as the shoulder blade and is a large, flat, triangular bone of the shoulder. The clavicle is another bone in this area, but it is not described as a large, flat, triangular bone. The thorax refers to the chest as a whole, not a specific bone. Ribs and sternum are also bones of the chest, but they are not the correct answer based on the given description.

The thorax refers to the region of the body between the neck and the abdomen, which includes the chest, shoulder, and back. It is a bony cage that protects vital organs such as the heart, lungs, and other internal organs. The term "thorax" is used to describe the entire region, while the other options listed (ribs, scapula, sternum, clavicle) are specific bones within the thorax.

The correct answer is Carpus. The carpus is a group of eight small, irregular bones in the wrist that are held together by ligaments. It is a flexible joint that allows for movement in the hand and wrist. The other options listed, such as phalanges, ulna, metacarpus, and radius, are also bones in the arms and hands, but they are not specifically related to the wrist joint like the carpus is.
