Joints

In these types of joints the fibers are very short and allow for little of no movement. Synarthroses joints come together at a point at which adjacent bones are bound

during these movements, the angles of those joints, as well as the muscles involved during the

A joint is a junction of two or more bones and is commonly referred to as an articulation.Without joint in the body no movement will be possible.There are three types of joints immovable/fibrous where no movements are possible(example- cranium).Slightly movable/cartilaginous joint is a joint

Agatha Christie once said, “Every murderer is probably somebody’s good friend.” Unfortunately for Max, his good friend was his murderer. Ray was invited to a housewarming party because he was considered to be one of his good friends. It is very clear that after studying the case, Ray Leetuff is Max’s murderer because of his motives, testimonies, and the physical evidence found that binds him to the crime.

There are about 600 muscles in the body working together to create movement. Muscle contractions pull both ends of the muscle towards one another. One bone attached to each muscle is always more stabilized than the other. The less stabilized bone moves during muscle contraction due to the weaker stability. The points of attachment determine which bone will move. The least movable part is called the origin; it is the part that attaches closer to the midline of the body. This leaves the most movable part called the insertion. Each of these points can be identified in individual muscles to assist trainers in understanding how the muscles and joints work together to create motion.

For the human joint anatomy project, our group decided to research and construct the elbow joint. The following is a report and summary of the project including roles taken, challenges faced, solutions derived, and ultimately, contribution and experiences of both partners.

Joints are the connecting points where two bones meet. They allow the human body to be flexible. Muscles are also necessary for movement. They pulls bones are allow them to move. Tendons attach muscles to bones while ligaments attach bones to bones. The central nervous system stimulates muscles to contract when they are stimulated by “messages”, or impulses, that are sent from motor nerves and the bursae are fluid filled sacs between joints that provide protection

The knee is a hinge-type, diarthrotic, or freely moveable joint. Also referred to as a synovial joint, the 2 articulating ends of bone are encased in a capsule that lubricates the joint with synovial fluid to reduce friction.

Ligament - Ligaments determine how much the joints can move so each joint is stabilized.

The film and novel of To Kill a Mockingbird complement each other in many ways due to their similarities, but the book can accomplish things that the movie can’t due to it’s ability to tell. The book is written in a narrated voice, making it hard to tell the entire story through a film. The thoughts and feelings of the characters can’t always be felt and understanded through a film because of its limited time allotted, but through a book you are able to know and interpret everything. There are missing parts of the plot, along with many other differences of the story because of this. While the book is very similar to the movie and vis versa, there are many differences.

Jumping (bilateral): Hip and knee is in extension, while ankle is in plantar flexion, and shoulder abduction and flexion while in the air.

It is a modified hinge joint that allows flexion and extension, as well as anterior and posterior gliding and minimal rotation. The bony articulations of the knee include medial and lateral tibio-femoral articulations and a patello-femoral articulation. There is also an articulation between the head of the fibula and the tibia, but the fibula does not bear weight and is not considered part of the knee joint itself. The afore-mentioned articulating surfaces are incongruous, and the stability of the knee relies mostly on the integrity of the supporting muscles and ligaments. The muscles that span the knee are the quadriceps anteriorly, the hamstrings and gastrocnemius posteriorly, and the tensor fascia latae (iliotibial band) laterally (Moore 2014).

The shoulder is a ball and socket joint which allows it a flexion and extension motion.

The left metatarsophalangeal and interphalangeal (great and lesser toes) joints are held at slight flexion pressed against the ground by a concentric contraction of the flexor halluces longus, flexor digitorum longus, flexor digitorum longus. The left talocrural (ankle) is plantar flexed using a concentric contraction of the gastrocnemius and the soleus. The right talocrural (ankle) is plantar flexed by a concentric contraction of the tibialis anterior, extensor digitorum longus, peroneus tertius. The left tibiofermoral (knee) joints are being extended by a concentric contraction of the quadriceps muscles (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius). The right metatarsophalangeal and interphalangeal (great and lesser toes) are being held plantar flexed due to an isometric contraction of the flexor halluces longus, flexor digtorum longus. The right tibiofermoral (knee) joints are flexed at a 90-degree angle by a concentric contraction of the biceps femoris, semitendinous, semimembranosus. During this phase the left acetabular fermoral (hip) joint is flexed due to an eccentric contraction of the rectus femoris, pectineus, iliacus, and psoas. The right acetabular fermoral (hip) joint is at slight extension due to a concentric contraction of the biceps femoris, semitendinosus, semimembranosus, and the gluteus

Synovial joints are the most common joints in the skeletal system and are also known as the freely moveable joints. They are not directly connected which is why it allows a great amount of movement. As with most other joints in the body, synovial joints achieve more movements. The synovial joints consist of six different types of joints.
