Do you capitalize the names bones...like humerus vs. Humerus?

In general, bone names are not capitalized unless they are named after a specific person or place. So, "humerus" would typically be written in lowercase, unless you are referring to the specific bone or using it in a title where capitalization is required.

What joint connects the atlas to occipital condyle?

The occipital condyles allow the head to turn side to side.

Temporary joint in which bones are united by bands of hyaline cartilage?

Synchrondoses, a form of cartilagous synarthrosis. Found between two ossifying centres of bone in development. Example, the epiphyseal growth plate between the epiphysis and diaphysis in developing long bones.

What happens if you crack your skull?

It all depends on how much energy is transferred to the brain, how big the crack is and where it is located.

It may lead to concussion injury

It may lead to Cerbrospinal fluid leak

Or the patient may not have any symptoms at all

If the patient has a depressed fracture along with the crack it may cause a mass effect on the brain.

Haematoma caused by the crack may cause mass effect on the brain.

It may also cause what is call panda eyes or racoon eyes due to ecchymosis and extravasation of blood underneath the skin.

What are human bone made of?

human bones consist of smooth and rough cartilidge which allows for movement, a hard layer of compact bone gives it strength, inside the bone their are 2 types of marrow: yellow marrow-which stores fat cells and minerals, and red marow- where red blood cells are made. inside the compact bone their is also a layer of spongy bone- this is like honeycomb, it makes the bone strong without being too heavy

What bony landmark is defined as a smooth rounded knob?

The condyle is a bony landmark defined as a smooth rounded knob. It is often found at the ends of long bones, such as the femur or mandible, and functions in articulating with other bones to allow movement at joints.

How do you know a right from left femur?

The right femur is typically larger and more robust than the left femur. The head of the femur also angles slightly inward on the right side. Additionally, the greater trochanter is located more laterally on the right femur compared to the left.

What is the weight of the compact bone?

The weight of compact bone can vary depending on factors such as age, gender, and individual differences. On average, compact bone tissue comprises about 80% of the weight of the human skeleton. The weight of a compact bone can range from a few grams to several kilograms.

What is the name of the superior portion of the sternum?

The manubrium or manubrium sterni is the upper part of the sternum. It articulates with the clavicles and first two ribs.

What is the large bone in the thigh called?

The long bone in the thigh is called the femur.

Why does the brain have joints?

The brain does not have joints. Joints are primarily found in the skeletal system to facilitate movement between bones or cartilage. The brain is a soft, gelatinous organ that is protected by the skull and is not connected through joints like the rest of the body.

Who plays Booth on Bones?

David Boreanaz portrays the character of Seeley Booth in the TV show "Bones." Booth is an FBI special agent who partners with forensic anthropologist Dr. Temperance Brennan to solve crimes.

What is the size of a lumbar pillow?

A lumbar pillow is designed for the user's lower back to provide comfort and support. Usually, a lumbar pillow's purpose is to assist with posture while the user is sitting up. Lumbar pillows are more firm than head pillows and are usually made with memory foam or high resiliency foam.

What type pf bone is the fibula?

The fibula is a long and slender bone located in the lower leg, beside the tibia. It is classified as a type of long bone. The fibula mainly serves as a support for the leg muscles and has a minor role in weight-bearing compared to the tibia.

What on the outside of the long bone is made of hyaline cartilage?

Hyaline cartilage

actually it is articular cartilage that lines the end of long bones. depending on the age of the body and whether it is a fetus or child/adult. hyaline cartilage disappears around the 6th week old fetal development and is replaces with osseous tussue. there is a region, farther from the marrow cavity, that consists of typical hyaline cartilage that shows no sign of transformation into bone in the early years of growth. it is in the "zone of reserve cartilage"

The portion of the sternum that articulates with the clavicles is the?

The manubrium is the superior portion of the sternum and what articulates with the clavicles.

Blood vessels that nourish the osteocytes or bone cells travel to the area through the?

Blood vessels that nourish the osteocytes travel through the Haversian or Volkmann's canals within the bone tissue. These canals provide a pathway for blood supply to reach the osteocytes, ensuring they receive necessary nutrients and oxygen for their metabolic activities.

What is one of the main functions of the skeletal system?

The skeletal system in the body provides the shape, supports and protects organs and the soft areas of the body. Its others functions are bodily movement, producing blood for the body, and storing minerals that the physical structure needs.

Shape and Support

The skeleton is made up of various bones and provides the framework for the body. Thus, the skeleton provides the basic shape and structure for the body. The bones are like the structural members of a building, and all of the organs, muscles and skin are incorporated with the bones, just like the furnishings, rooms, walls, and finishing of a building.

Protection

The skeleton protects organs in the body. Bones can cover and protect many of the major organs.

Cranium: protects the brain

Ribs/sternum: protects the lungs, heart and digestive organs

Pelvis: protects and supports the digestive and reproductive organs

Spinal column: protects the major nervous system branching into the entire system, and holds up your body like the trunk on a tree.

Skull: mandible, maxilla and teeth protect the tongue and buccal cavity.

Blood Cell Production

Inside of the long bones there is a cavity that is filled with a substance called Bone Marrow that produces blood cells and repairs damaged blood cells.

Movement

The bones of the skeleton are the levers that help the body move in different directions and in different ways. Bones anchor muscle to provide movement. The bones by themselves can't move without the muscles that are connected to them.

Mineral Storage

Mineral is a substance that the body needs to carry out all of the bodily functions like thinking, breathing and moving around. One of the minerals that the body needs is calcium. Calcium is a major part of bone, and this is where the body stores its calcium. The less calcium the bone has, the weaker it will become. In case the body does not get enough calcium from the daily intake of food, it will take the calcium it needs from the bones.

How did Dave levey break his wrist?

How many bones does a bush baby have?

None. They are made only of muscle. That is why they are less smart than us. Their brains aren't protected, so they lose brain cells very quickly, even though they are born with as many as a human.

What are the two division of skeletal system?

The axial and appendicular are the two divisions in the skeletal system.

The axial skeleton consists of bones that form the axis of the body and support and protect the organs of the head, neck, and trunk the skull, the sternum, the ribs, the vertebral column

The appendicular skeleton is composed of bones that anchor the appendages to the axial skeleton. The upper and lower extremities, the shoulder girdle, the pelvic girdle

What is the only moveable bone in the face?

The mandible, also known as the lower jaw bone, is the only moveable bone in the face. It is unique in that it can move up and down, as well as side to side, enabling actions such as chewing and speaking.

What bone contains sockets of upper teeth?

The maxilla bone contains the sockets of the upper teeth in the human skull. It forms the upper jaw and plays a vital role in supporting and securing the roots of the upper teeth within the oral cavity.

What are six types of bone?

  1. Long bones, such as the femur and humerus.
  2. Short bones, like the carpal and tarsal bones.
  3. Flat bones, including the skull and ribs.
  4. Irregular bones, such as the vertebrae and hip bones.
  5. Sesamoid bones, like the patella (kneecap).
  6. Sutural bones, found within sutures of the skull.

The tough fibrous connective tissue covering of a bone?

The tough fibrous connective tissue covering of a bone is called periosteum. It contains blood vessels, nerves, and cells involved in bone formation and repair. Periosteum helps in protecting the bone and facilitating nutrient exchange for bone health.
