Connective Tissues and Joints Flashcards
What is a Joint?
A joint is where two or more bones meet and allows your bones to attach and move. Some joints are rigid and moveable whereas some are immoveable.
Define Fibrous and give some examples.
Fibrous joints has no movement. Some examples of fibrous joints are skull, pelvis, radioulnar.
Define Cartilaginous and give some examples.
Cartilaginous joints has slight movement and are joined by cartilage which is a strong flexible connective tissue that protects our joints and bones. Some examples of cartilaginous joints are ribs attaching to the sternum and the lumbar vertebrae.
Define Synovial joints and give some examples.
Synovial joints has free movement and are connected by ligaments. Some examples of synovial joints are the cervical vertebrae and the thoracic vertebrae.
True or False: The joints that allow the most movement are the strongest and most durable.
False, The joints that allow the most movement are the most unstable and vulnerable.
What is the two connective tissues you find in joints?
Tendons and Ligaments
What does are Tendons and what do they do?
Tendons are a fibrous connective tissue that attach muscles to bone and acts like levers to move your bones as your muscles contact and expand. Essentially, they help you move your limbs (your appendicular skeleton)
What are tendons susceptible to?
Tendons help prevent muscle injury by absorbing some of the impact your muscles receive when doing various movements along with being highly resistant. However, they are not stretchy which means they can be easily injured when strained.
What are Ligaments and what do they do?
Ligaments are fibrous connective tissues that attach bone to bone and serves to hold structures together like bone, joints and organs.
What are Ligaments susceptible to?
Ligaments sprains are common due to them being a weight bearing ligament that are under a lot of stress especially if you play a full contact sport or one that involves in moving in a lot of directions.
What are the 6 types of synovial joints?
The six types of synovial joints include pivot, hinge, ball and socket, glide, condyloid and saddle.
What does the Pivot joint allow you to do? Give an example of a Pivot joint.
Pivot joints are synovial and allows you to have a rotary movement around a single axis. An example of a pivot joint is radius/ulna joint.
What does the hinge joint allow you to do? Give an example of a hinge joint.
The hinge joint allows the movement of extension and flexion. An example of a hinge joint is your elbow.
What does the ball and socket joint allow you to do? Give an example of a ball and socket joint.
The ball and socket joint has the biggest range of motion that includes back forth, sideways and rotating motions. An example of a ball and socket joint is your ankle.
What does the gliding joint allow you to do? Give an example of a gliding joint.
A gliding joint allows movement between bones where slight rotations can occur. An example of a gliding joint is your toes.
What does the condyloid joint allow you to do? Give an example of a gliding joint.
The condyloid joint allows you to do flexion, extension, adduction, abduction and circumduction. An example of a gliding joint includes your wrist and knuckles.
What does the saddle joint allow you to do? Give an example of a saddle joint.
The saddle joint allows similar movement to the condyloid joint although with greater range of motion. An example of a saddle joint is your thumb which can move more freely than your wrist
Which joint do we care most about in sports and Phys Ed?
The synovial joint is one of the most important joint as it allows the greatest amount of motion which is needed to move freely and complete skills.
What are the two most freely moveable joints in our bodies?
The ball and socket (hip, shoulder) and hinge joint (elbow, knee) are the two most freely moveable joints in our body.
