The plane, or gliding, type of synovial joint provides the least amount of movement, says Springfield Technical Community College. This type of joint is found between the vertebrae, the carpal bones in the hand and the tarsal bones in the foot.Continue Reading
Synovial joints are composed of two bones separated by a fluid-filled sack. Most of the body's movable joints belong to this classification. The type of synovial joint with the greatest range of motion is the ball-and-socket, which includes the joint that connects the humerus to the shoulder.
The gliding or planar type is sometimes able to move in several directions, but the distance of this movement is tightly constrained. Examples of this type include the joints that connect vertebrae and many of the joints among the bones that make up the hands and feet. The range of motion in these hand and foot bones is limited to a short-range sliding motion in a single direction.Learn more about Human Anatomy
A saddle joint is a synovial joint that allows side-to-side and back-and-forth movement with small amounts of rotation. The most obvious example in the human body is the joint at the base of the thumb.Full Answer >
Selective permeability is the concept that states the cell membrane does exert some control over what goes into the cell or out of the cell, according to Springfield Technical Community College. Cells allow molecules or compounds into the cell via passive or active transport.Full Answer >
Veins have valves to prevent the backflow of blood, according to Professor Tamarkin at Springfield Technical Community College. Veins carry blood from the body back to the heart, so they need these one-way valves to prevent blood from flowing backward.Full Answer >
Blood travels into the glomerulus via the afferent arteriole, explains Dr. Dawn A. Tamarkin of Springfield Technical Community College. The glomerulus is a bundle of capillaries with split pores for filtering blood. Glomerular filtration is the first step of urine production and occurs within the renal corpuscle of the kidneys.Full Answer >
