Gliding Joint

Gliding Joint

Allows the bones to glide past one another and they can go any direction such as left and right and up and down. Located in the ankle wrist and spine.

Hinge Joint

Allows for bending and straightening movements.Located in the fingers, toes, elbows and ankles.

Condylar Joint

Allows for flexion extension, and abduction

Saddle joint

Allows for flexion, extension, abduction, and adduction as well as circumduction. Located in the thumb, thorax, and heel.

Ball and Socket Joint

Allows for forward, backward sideways and rotating movements.Located in the shoulder and the hip.

Pivot Joint

Allows rotation internally and externally.Located in the wrist neck and elbow.

What are the parts of the vertebrae?

Cervical, Thoracic,Lumbar, Sacrum, Coccyx

What Is the part of the vertebrae that is the smallest.

Cervical vertebrae

How many parts does the Cervical vertebrae have?

7

What is the middle vertebrae?

Thoracic vertebrae

How many parts does the Thoracic vertebrae have?

12

What is the lowest part of the vertebrae?

Lumbar

How many parts does the lumbar vertebrae have?

5

Where is the sacrum?

The triangular bone that is just below the lumbar vertebrae. It is five segments fused into a large bone.

Where is the coccyx?

A triangular bone at the very bottom of the vertebrae below the sacrum.

How do bones remodel and reshape?

resorption (osteoclasts digest the bone), reversal (mononuclear cells appear on the bones surface, and formation (when osteoblasts lay down new bone until the resorbed bone is completely replaced).

What is the difference between male and female pelvic regions.

Males have a more narrow pubic arch while women have a wider pelvic arch because of the birth canal. Males look like a u and women look more like a w.

What are the two bones of the forearm?

Radius and Ulna

What is the purpose of the bones in your forearm and why are they important?

The radius and ulna are used for support but also allows your wrist and hand to rotate smoothly.

What bones articulate with the scapula?

Humerus and Clavicle

Where is the glenoid cavity?

The lateral part of the scapula.(simple terms- the side where your ball and socket joint of the arm connects)

Where are the medial and lateral epicondyles found?

Medial epicondyles -Inside the elbow

Lateral epicondyles- on the outside of the elbow

What is the purpose of epicondyles?

The epicondyle attaches muscle and connective tissue to bone, providing support to this musculoskeletal system.

What is the function of the pelvic girdle?

The main functions of the pelvic girdle are to transfer the weight of the upper body and lower limbs when sitting or standing, and provide attachment places for the muscles that help with movement and posture. It also provides support and protection for the abdominopelvic structures.

How many carpals are found in the hand?

8

How many metacarpals are found in the hand?

5

How many phalanges are found in the hand?

14

What are the functions of the skeletal system and why is it important?

It is important because it supports the body and the attachment of muscles. The skeleton protects the organs of the cranial and thoracic cavities from injuries, and it houses and protects bone marrow within its cavities.

What are synarthroses?

immovable joints or bones that are in really close proximity. Such as plates in the skull, and the joint found between the first pair of ribs and the sternum.

What is the appendicular part of the skeleton?

The arms, shoulders, pelvis, and your legs all the way down to your toes.

What is the axial part of the skeleton?

From the top of the head,your neck, ribs,vertebrae all the way down to the coccyx.

Tarsals, Metatarsals, phalanges

What is the diffrence between placements of the tibia and fibula? ( this should help with locating where each bone is)

Tibia is attached to the front of your knee and fibula is attached to the part behind your knee.

What is the order of the bones in your hand called starting from the wrist going down to fingers? ( this should help with locating where each bone is)
