It is called a diagonal.
No, it's a chord. The area between a chord and the circumference is a segment.
The dorsal rami of a single spinal segment monitor sensory information from the skin on the back of the body, including the muscles and joints in that region. They provide sensation for a specific dermatome, which is a specific area of skin innervated by the spinal nerves from that segment.
The Thoracic Spine is the least mobile segment of the spinal column and it contributes to it's share by lengthening dynamically during movement.
The facet joints help support weight-bearing and control movement between vertebrae of the spine. There are two facet joints (one on each side) at each spinal segment. These joints may degenerate. Degenerative joint changes are common in the older population, but may occur in younger adults, particularly with prior trauma.
A crayfish has six tail joints, collectively known as the abdomen. These segments, or somites, are often referred to as the pleon and are flexible, allowing the crayfish to swim by flexing and extending its tail. Each segment contributes to the overall structure and movement of the crayfish.
To add extra joints to your Spore creature, enter the Creature Editor and select the segment of your creature where you want to add the joint. Use the "Add" tool to place a new joint segment, which can be adjusted for positioning and rotation. You can also customize the creature’s limbs and appendages to enhance mobility and flexibility. Experiment with different joint placements to achieve the desired appearance and functionality for your creature.
the different groups of joints in the body are saddle joints gliding joints hinge joints and ball and socket joints .
The subclasses of synovial joints are plane joints, hinge joints, pivot joints, condyloid joints, saddle joints, and ball-and-socket joints. These subclasses vary in the types of movement they allow and the shapes of the articulating surfaces of the bones involved.
sliding joints hinged joints fixed joints
Hinge joints, ball-and-socket joints, ellipsoid joints, saddle joints and pivot joints.
what are construction joints and movement joints
There are two general types of joints, movable and immovable. Under the movable category there are four types of joints: Hinge joints: in knees and elbows Pivot joints: in neck Gliding joints: in wrists and ankles Ball-and-socket joints: in shoulders and hips
