Which is smaller a myofibril or a myofiber?
Short Answer:A myofibril is smaller than a myofiber (muscle fiber).Long Answer:Skeletal Muscle Hierarchy:Muscle OrganPerimysium = white fibrous connective tissue & areolar connective tissue that surrounds each fascicleFascicle = bundle of skeletal muscle fibersEndomysium = areolar connective tissue that surrounds each muscle fiberMuscle Fiber ( Myofiber) = a muscle cellMyofibrils = contractile protein organellesMyofilaments = contractile proteins composed of:thick filaments = made of myosinthin filaments = made of actin
What is the Part of the urethra within the Urogenital diaphragm?
The part of the urethra within the urogenital diaphragm is called the membranous urethra. It is a short segment of the urethra that passes through the urogenital diaphragm, which is a sheet of muscle and connective tissue located between the pelvic cavity and perineum.
Is a knee cap a short bone?
Yes; the knee cap, whose technical name is the patella, is part of the skeletal system. Sometimes referred to as a "floating" bone, the patella is not directly connected to any other bones. It is surrounded by muscles instead, the bottom portion of which is connected to the tibia, or shin, by patellar tendons. The patella is triangular in shape and normally resides in front of the knee joint, shielding it from possible damage.
What is the CMC joint in your body?
The CMC joints in the body are joints in the wrist used as bases for the metacarpal bones. You can get more information about this at the Wikipedia. Once on the website, type ":Carpometacarpal joint" into the search field at the top of the page and press enter to bring up the information.
What connect bones at a joint?
As with any structure, the human body is built upon a framework that is constructed to carry out a wide range of functions. The bones, ligaments, and tendons are each essential parts of the human framework, integrated into a mechanism, the skeleton, that is crucial to the movement, stability, protection, and growth of the entire body.There are approximately 206 bones in the human body. Bones generally act as connective tissue within the body. All bones are composed primarily of the mineral compound, calcium phosphate, which is a very hard substance, with a lesser amount of collagen (a protein). For this reason, bone is structured as a relatively brittle matrix, although the softer collagen cells lend some degree of elasticity when a bone sustains trauma. Not all bones possess the same characteristics, nor do all bones fulfill the same purpose within the skeleton.Because bone is a hard, white, and seemingly sterile object, it is perhaps difficult to regard the human skeleton as an organism. The bones, ligaments, and tendons are not only a coordinated frame upon which human muscles and organs are attached and contained, the skeleton and the rest of the body are an interconnected biological device.Ligaments are the skeletal components that connect bones to other bones to create a joint, a flexible structure that is capable of movement and of bearing both weight and external forces applied to it. Ligaments are made of collagen, formed into short, fibrous bands. All of the body ligaments are important to efficient physical movement. However, the ligaments that are of special significance are the anterior cruciate ligament (ACL), the connector between the femur and the tibia (lower leg bone) essential to knee function, and the ulnar cruciate ligament (UCL), an elbow structure essential to the success of any baseball pitcher.Tendons have a similar construction to that of ligaments: they are strong, fiber-like connectors. However, rather than connecting bone to bone, tendons connect muscle to bone, providing stability and a significant degree of resistance to external forces. Large tendons such as the Achilles tendon, which connects the gastroceus (calf muscle) and the calcaneus (heel bone), are able to withstand force due to the flexing qualities of the supple collagen that forms a large portion of the tendon structure. As with an ACL or UCL injury, a tear or rupture of the Achilles tendon is a debilitating occurrence.There are two types of bones: cortical bones and cancellous bones. Cortical bone has a denser, more compact structure than does the cancellous bone, and comprises the greater proportion of the skeleton mass. Most of the longer bones in the body are cortical, such as the femur (thigh bone). The long bones are hollow, and the center of the bone is filled with a substance known as yellow marrow. At the end of each long bone is an area known as the epiphysis, which is usually composed of cancellous bone cells; the marrow in this portion of the long bones is red marrow.Ligaments hold the bones together. They stretch from one bone over a joint to another bone.By ligaments.
Where can a ligament be found?
Ligaments are located at most of the joints. They keep the joints together.
What tissue determines the flexibility of a joint?
Nope. A joint is flexible if the muscles (with their attached tendons) are not spasmed, and if the ligaments are not too short. Stretching can frequently lead to increased flexibility (and mobility). This stretching tends to lengthen both the muscles and ligaments. On the other hand, if a joint is too hypermobile (unstable), exercise against resistance will tend to shorten these structures (first muscles, later ligaments), and can be very helpful...e.g., in the neck, which tends to be the most unstable part of the human spine. --Dr. Halle
What is the definition of ligament?
A ligament is a fibrous connective tissue that connects bones to other bones and helps to stabilize joints by limiting excessive movement. They are strong and flexible structures that provide support and assist in maintaining the proper alignment of bones during movement.
Muscle and connective tissue in the stomach?
Short answer: Tendons Medium Answer: Around the stomach lie numerous tendons. Long answer: The stomach is lined with smooth muscle, with has tendons in various points within it. The stomach, along with the entire body, is covered in fascia, which is a jumble of tendons, nerves, blood vessels, and other important things.
How many shapes of bones are in your body?
* 1.1 * 1.2 Connective tissue * Epit * 1.3 Muscle tissue * heliu * 1.4 Neural tissue * m * 1.1 Epithelium
What is myelination and why is it so important?
Nerve cells are covered with connective tissue. So that current does not flow from one cell to other by short circuit. This is very important for the integrity of the nervous system. This is just like insulation of electric wires. So if the wires are not insulated you will get the gadgets short circuited.
What is blood short answer?
Blood is a liquid connective tissue composed of cells and an extracellular matrix. The matrix being the plasma and the cells being erythrocytes (red blood cells), platelets, and 5 types of leukocyte (white blood cells).

Where does the joint venture meet the needs of both the parteners where does it fall short?
At the joint
What are the requirements of a good joint in an conductor?
A good joint in a conductor should ensure electrical continuity, mechanical strength, and insulation resistance. It should also be made with appropriate materials for the application and be securely connected without any loose or exposed parts. Additionally, the joint should be properly insulated to prevent any electrical faults or short circuits.
