Which bone in the human body is named after the Italian for flute?
The early Latin word for flute was "tibia", the same word for a shinbone. The early flute was made of bone, rather than wood which could split or break. It was associated with the recorder about 5,000 years ago.
How are the vertebrae numbered in the human spine?
The vertebral column which also none as the spinal column is divided into segments made of 32 bones. The Cervical vertebrae has 7 bones which make up the neck. The Thoracic vertebrae has 12 bones and forms the upper back. The Lumbar vertebrae has 5 bones and forms the lower back. The fifth articulates with the sacrum which in turn articulates with the coccyx. The cervical, thoracic, and lumbar regions consist of individual vertebrae. The Bones are labeled according to the region. Example the Cervical region is labelled C-1-7, the thoracic is labelled T-1-12 and the lumbar area is labled L-1-5. The Sacrum consists of fused components of 5 sacral vertebrae. The Coccyx consists of 3-5 coccygeal vertebrae that have fused together.
What anion critically involved in bone formation?
Phosphate ions, in the form of hydroxyapatite, are critically involved in bone formation. They provide structural support and strength to bones by forming mineral deposits along with calcium ions. Additionally, phosphate ions play a key role in regulating bone metabolism and growth.
A nuclear bone is not a scientific term or concept. It may be a misunderstanding or a mix-up of terms. The nucleus is a part of a cell that contains genetic material, while bones are hard structures that make up the skeletal system.
joints. heres the definition of joints:
joint |joint|
noun
a structure in the human or animal body at which two parts of the skeleton are fitted together.
How many cervical thoracic and lumbar vertebrae are there?
Absolutely! They have features unique to the region they are found in, relating to structure and therefore function. Typical cervical vertebrae (C3-C6) usually have bifid spinous processes which point slightly inferiorly. The spinous processes on lumbar vertebrae are oblong in shape and point directly posteriorly. The articular facets of cervical vertebrae face superior-inferiorly, whereas lumbar articular facets face medial-laterally. Cervical vertebrae have transverse foramen on right and left(containing the vertebral arteries), lumbar have none. They have mamillary processes on their superior articular processes. The bodies of lumbar vertebra are larger and thicker than cervical vertebrae, though they are oval/kidney shaped shaped in both regions. The transverse processes of lumbar vertebrae are much longer, for muscle attachment. Cervical vertebrae have anterior and posterior tubercles extending from their transverse processes. The pedicles of lumbar vertebrae are slightly longer and more defined than those of cervical vertebrae. I think that covers everything, let me know if you think of anything else!
What body tissue adds stability to the knee joint?
The meniscus, which is made of fibrous cartilage, adds stability to the knee joint. It acts as a cushion between the bones of the knee and helps distribute weight evenly across the joint.
At what age do a child's bones harden?
A child's bones continue to harden and develop until around the age of 18-25, depending on the individual. The process of bone development and hardening is called ossification, where mineral deposits gradually strengthen the bones over time.
Spiders do not have a skeleton on the inside of their body. They have what is called an "exoskeleton" which is basically a hardened outer shell that covers their entire body.
Spiders have an exoskeleton.
The bones are proximal to the skin?
Proximal means "closer to the trunk of the body than" and is usually meant on a limb, for example the femur is proximal to tibia. The bones are deep to the skin.
What carpal bone is found in the anatomical snuffbox?
The scaphoid, or navicular bone is located within the anatomic snuffbox. Pain in this location after a fall on the hand or wrist may indicate a fracture of the scaphoid.
How does the skeletal and muscular systems work together to raise and lower the forearm?
The biceps and triceps muscles work synergistically; the biceps muscles contracting concentrically and the triceps muscles contracting eccentrically when the forearm lifts, and it's the exact reverse when the forearm lowers.
The tibia is one of the two bones in the lower leg, responsible for bearing weight and providing stability when standing or walking. It also plays a role in anchoring muscles and connecting to the ankle joint to facilitate movement.
He would be appreciating her facial structure since the zygomatic bones are the cheekbones in the face. Complimenting someone's zygomatic bones might be a unique way of saying they like her cheekbones.
How many bones in a humens brain?
There are no bones in the human brain. The human skull protects the brain, which is made up of soft tissue.
What is skeletal system made up of?
the human skeletal system consists of the skeleton. More specifically all bones and joints. not the spinal cord , but the spine. The spinal cord is inside the spine and is part of the nervous system. The definition is, supports and move the body and protect some of the organs.
hope this helps :)
Why is yellow bone marrow yellow?
Bones are not usually white. More light yellow. Only when you bleach your bones are they white.
But bleaching causes deterioration.
Calcium and blood cells cause the color of your bones.
X-Rays also make it look white.
HEALTH: Bones sensitive if not kept healthy. You can stop this by drinking milk and avoiding soda.
What vertebral column bears a peg-shaped dens that acts as a pivot?
The cervical vertebrae, specifically the second cervical vertebra (C2) known as the axis, bear a peg-shaped dens (odontoid process) that acts as a pivot for rotation of the atlas (C1) and allows for the turning of the head from side to side.
Where is the funny bone located in the body?
At your elbow where the Humerus bone ( upper arm )connects with the radius and Ulna ( lower arm )
It is not a bone but a spot on the elbow where the ulnar nerve runs close to the surface and produces a sharp tingling sensation if knocked against the bone but it hurts really bad if you hit it and I'm sure everyone has done that at least once....
AnswerIt's your elbow, it's only a nick name though, it's called the funny bone because it connects the 'humerous' or upper arm bone to the bones in your lower arm.I don't know why ^^^ is listed under answer because the first answer is correct. the second is absolutely incorrect. There is no 'bone' at all. Just the largest exposed nerve in the body!
An ultrasound of the pelvis is a medical imaging test that uses high-frequency sound waves to create images of the reproductive organs, bladder, and surrounding structures in the pelvis. It is commonly used to diagnose issues such as ovarian cysts, uterine fibroids, and pelvic inflammatory disease.
There are 27 in each hand and foot.
Despite being short in size, the phalanges have growth plates that ultimately form an epiphysis head at either end of the shaft of the bone causing them to be longer than they are wide so they are actually classified as long bones.
Long bones are classified as being longer than they are wide while short bones are typically cubed shaded.
What is the name of the spin bone?
The spinal column consists of 33 irregular bones called vertebrae. Starting from the neck, there are seven cervical vertebrae. The first two vertebrae have specific names and are called the atlas and axis respectively. The next 12 vertebrae are called thoracic vertebrae, followed by five lumbar vertebrae, which are the largest of the spinal bones. Next, there are approximately five sacral vertebrae that are separate from each other as a young child, but fuse together as one bone called the sacrum in adults. Finally, the coccyx, more commonly called the tailbone, consists of 3-5 small bones that fuse together in adults.
What makes the femur the strongest bone in your body?
The femur is the strongest bone in the body because it supports the entire weight of the body during activities like walking, running, and jumping. Its cylindrical shape and structure help distribute forces and resist bending, making it highly durable and less prone to fractures. Additionally, the femur is reinforced by dense cortical bone and strong trabecular bone in its proximal and distal regions.
