Skeletal System

The hip joint if formed by the head of the femur and the acetabulum, which is a "cup" or concave structure integral to the pelvis. Below you'll find links to the related Wikipedia post where you can find more information and pictures.

Compact bone tissue is arranged in concentric layers called lamellae around a central canal that contains blood vessels and nerves. These layers give compact bone its strength and resilience, helping to support the body and protect vital organs.

After your period you will be dryer and as you get closer to ovulation mucus will gradually increase and it will be sticky and cloudy (creamy). RIGHT before you ovulate mucus will increase even more and it will become clear and very slippery, (like egg white) and stretchy. Ovulation will occur at about this time. After ovulation it will become sticky and cloudy again, and mucus will decrease.

Having a backbone composed of separate vertebrae allows for flexibility and movement in the spine. This structure also provides protection and support for the spinal cord. Additionally, the articulation between vertebrae allows for shock absorption and distribution of forces during activities like running or jumping.

Enamel is the hardest tissue in the body because of the very high concentration, about the 96%, of mineral salts. The remaining 4% is water and organic m

Multiplying the length of the femur by 2. 6 and adding 65 to it should be roughly the person's body height in centimeters. However, the sex and race of the person can affect this relationship between the femur and body height.

As you touch the area of your temple region about as high as your ear straight forward towards the nose you can feel the muscle there which can be found easily by clenching your jaw repetitively, go to the top of the muscle towards the peak of your head about two inches above the edge of the muscle and that is the supperiorlateral part of the cranium. Often injuried in a head trauma. Hope that helps.

1. The vertebral column usually consists of 33 vertebrae: 24presacral vertebrae (7 cervical, 12 thoracic, and 5 lumbar) followed by the sacrum (5 fused sacral vertebrae) and the coccyx (4 frequently fused coccygeal vertebrae).

Yes, nerve stimulation is necessary for skeletal muscles to contract. This stimulation causes an action potential to travel down the motor neuron, leading to the release of acetylcholine at the neuromuscular junction, which triggers muscle contraction by causing calcium release in the muscle fiber. Without this nerve input, skeletal muscles would not be able to contract voluntarily.

The acromium is a region of your shoulder blade. The clavicle is your collarbone. Where the two articulate or form a joint is the acromioclavicular joint. You can palpate this by following your collarbone towards your shoulder until you feel a notch. That is pretty much putting your fingers right on that joint.

The outward extension of the shoulder bone is called the acromion process. It forms the outer part of the shoulder blade (scapula) and contributes to the shoulder joint's stability and range of motion.

The iliopsoas muscle is a composite of two muscles, the iliacus and the psoas major, which work together to flex the hip joint. The iliacus originates from the iliac fossa of the pelvis, while the psoas major originates from the lumbar vertebrae.

"Esqueleto" is skeleton in Spanish.

That is called the rib cage. It consists of the ribs, sternum, and thoracic vertebrae, and its main function is to protect the internal organs, such as the heart and lungs.

The joints between the carpal bones are synovial joints, specifically gliding joints. These joints allow for small amounts of movement between the carpal bones to help with wrist flexibility and stability. The surrounding ligaments provide additional support to these joints.

No - the pectoral girdle refers to the shoulders. The two bones that make up the pectoral girdle are the scapula and clavicle.

Rib cage cramps or spasms can be caused by a variety of reasons, such as muscle strain, dehydration, or overexertion. Poor posture, stress, or certain medical conditions like costochondritis can also contribute to rib cage cramps. It's important to stay hydrated, practice good posture, and stretch your muscles regularly to reduce the risk of experiencing these spasms. If the cramps persist or are severe, it's best to consult a healthcare professional for further evaluation and treatment.

interosseous ligament, which connects the bones together and provides stability to the joint. It is commonly found in the ankle where the tibia and fibula are connected by this ligament. Injuries to the syndesmosis, such as a high ankle sprain, can lead to instability and pain in the joint.

The joints between the proximal phalanges and metacarpal bones are known as the metacarpophalangeal joints. These joints allow for flexion, extension, abduction, and adduction of the fingers.

A rounded process that usually articulates with another bone is called a condyle. Condyles are rounded projections at the end of a bone that form joints with other bones, allowing for smooth and stable movement.

The appearance of the growth plate closure, also known as the epiphyseal line, signals the end of bone growth in long bones. This happens when the cartilage in the growth plate is replaced by bone, indicating that growth has ceased in that particular bone.

The vomer is the inferior bone of the nasal septum. It is located in the midline of the nasal cavity, separating the left and right nostrils. The vomer articulates with the ethmoid bone superiorly and the maxillary bone anteriorly.

The acromion process articulates with the clavicle to form the acromioclavicular joint at the top of the shoulder.
