Joints and connective tissues quiz

A [blank_start]joint[blank_end] is the [blank_start]connection[blank_end] made between [blank_start]bones[blank_end] in the body which link the [blank_start]skeletal[blank_end] system into a [blank_start]functional[blank_end] whole. They are constructed to allow for different degrees and type of [blank_start]movement[blank_end].

Immoveable joints are also called [blank_start]fibrous[blank_end] joints. Slightly moveable joints are also called [blank_start]cartilaginous[blank_end] joints. Moveable joints are also called [blank_start]synovial[blank_end] joints.

[blank_start]Immovable joints[blank_end] are those that do [blank_start]not[blank_end] allow [blank_start]movement[blank_end] at joint locations. The bones are [blank_start]fused together[blank_end] so there is no joint activity. These joints are important for [blank_start]stability and protection[blank_end]. [blank_start]Slightly movable joints[blank_end] permit [blank_start]some movement[blank_end] but provide [blank_start]less[blank_end] stability than [blank_start]immovable[blank_end] joints. These joints can be structurally classified as cartilaginous joints, as bones are [blank_start]connected by cartilage[blank_end] at the joints. [blank_start]Synovial joints[blank_end] allow the joints to move in [blank_start]all directions[blank_end] allowing for [blank_start]greater mobility[blank_end] but they are [blank_start]less stable[blank_end] than [blank_start]fibrous and cartilaginous joints[blank_end].

An example of a fibrous joint is the [blank_start]cranium (head)[blank_end]. An example of a cartilaginous joint is the [blank_start]vertebrae[blank_end] or the [blank_start]sternum[blank_end]. An example of a synovial joint is the [blank_start]knee[blank_end], [blank_start]hip[blank_end], and [blank_start]shoulder[blank_end].

What are the three types of synovial joints

[blank_start]Ball and socket[blank_end]: The [blank_start]round head[blank_end] of a long bone fits into the [blank_start]hollow socket[blank_end] of another bone [blank_start]Pivot[blank_end]: One bone [blank_start]sits upon another[blank_end] bone and [blank_start]allows it to pivot[blank_end] [blank_start]Hinge[blank_end]: Two bones are [blank_start]joined together[blank_end] like the [blank_start]hinge of a door[blank_end]

Ball and socket: Moves in all [blank_start]directions with a free range of motion[blank_end] Pivot: [blank_start]Moves in a side ways rotation[blank_end] Hinge: [blank_start]Moves back and forward[blank_end]

Correctly identify the type of SYNOVIAL joint:

Identify the three different types of connective tissues

Cartilage: Cartilage is a [blank_start]resilient and smooth[blank_end] [blank_start]elastic tissue[blank_end], a [blank_start]rubber-like padding[blank_end] that covers and [blank_start]protects the ends of long bones[blank_end] at the [blank_start]joints and nerves[blank_end] Tendons: A tendon is a [blank_start]fibrous connective tissue[blank_end] which [blank_start]attaches muscle to bone[blank_end]. Help with [blank_start]movement of the body[blank_end]. Ligaments: A ligament is the fibrous connective tissue that [blank_start]connects bones to other bones[blank_end]. They help the body with [blank_start]support and stability[blank_end].
