Basic Human Anatomy: Extremities

Question 1

What allows us to move

Answer 1

These are your arms and legs. These bones along with their associated muscles and joints allow us to move in all sorts of directions.

Question 2

What are joints

Answer 2

Joints are where two bones connect. This connection is sometimes immovable such as the skull. Other times, this connection is mobile and the joint is what allows two bones that are next to one another to move in relationship to one another or the fancy word is articulate.

Question 3

What are main parts of joints

Answer 3

The main parts of any joint are going to be the bones, the ligaments and the joint capsule that is filled with fluid.

Question 3

Example of different types of joints

Answer 3

If you said the vertebrae with one another, the neck with the skull or possibly even the ribs with the sternum, you are on the right track.

Question 4

The main parts of any joint are going to be the bones, the ligaments and the joint capsule that is filled with fluid. What is that fluid called cand what does it do

Answer 4

That fluid is called synovial fluid and it’s like the grease that prevents the bones from rubbing against one another.

Question 5

What are ligaments

Answer 5

Ligaments are the connective tissue that connect two bones together.

Question 6

What are tendons

Answer 6

tendons are the connective tissue that connects muscles to bones.

Question 7

What is the shoulder and what does it do

Answer 7

The shoulder is a ball and socket joint that connects the humerus to the torso. On the proximal end of the humerus is the ball that fits in the socket and it is one of the most mobile joints in the body

Question 8

What is the socket of the shoudler made up of

Answer 8

The socket in this case is made up of the scapula and the end of the clavicle called the acromion.

Question 8

What is the humerus

Answer 8

the only bone of the upper arm

Question 8

What does the humerus form

Answer 8

It forms a joint with the lower arm at the elbow. The bones of the lower arm are the radius and ulna.

Question 8

What are the carpal bones

Answer 8

At the distal end of the radius and ulna, they form a joint with the bones of the wrist what are called the carpal bones.

Question 8

THe elbow

Answer 8

The elbow is also very mobile and is an example of a hinged joint with motion primarily in a single plane

Question 9

How many bones are in the wrist

Answer 9

There are eight bones of the wrist we just talked about that are called the carpal bones.

Question 9

What do the carpal bones do

Answer 9

The carpal bones connect to the bones of the hand which are the metacarpals.

Question 9

What are the bonds of the hand called

Answer 9

metacatpals

Question 10

How many metacarpals do we have

Answer 10

There are five of them one for each finger.

Question 11

What are the phlanges

Answer 11

There are three bones that form each finger and they are all called phalanges. So, your metacarpals form joints with your phalanges. Okay, so, that covers the upper extremity.

Question 12

Describe the upper extermiely from proximal to distal

Answer 12

the shoulder joint, the humorous, the elbow joint, the radius and ulna, the carpal bones of the wrist, the metacarpals of the hand and the phalanges that make up the fingers.

Question 13

What is the hip joint

Answer 13

This is also a ball and socket joint that is between the acetabulum of the pelvis and the femur of the upper leg. Similar to this shoulder, there’s lots of movement that is possible here.

Question 14

What is the femur

Answer 14

The femur is the only bone of the upper leg and it meets the lower leg at the knee.

Question 15

What are the bones of the lower leg

Answer 15

The bones of the lower leg are the tibia and fibula.

Question 16

How is the knee like the elbow

Answer 16

The knee is like the elbow and that it is a hinge joint that has movement in a single plane. The knee joint is reinforced with lots of ligaments.

Question 17

knee and liagments

Answer 17

They are just a couple of the ligaments that make up the knee joint.

Question 18

One special bone of the knee joint is the patella or your kneecap.

Answer 18

It protects the inner workings of the knee and also takes the brunt of a lot of falls.

Question 19

What do the fibula and tibia form

Answer 19

The fibula and tibia form the ankle joint with a bone in the foot called the navicular which is one of the tarsal bones.

Question 20

# ``` What are tarsals

Answer 20

The bones of the wrist are called the carpals and the angle are called the tarsals.

Question 21

medial and lateral malleolus

Answer 21

The bone that sticks out on the medial side of your ankle is the distal portion of your tibia. The bone that sticks out on the lateral side is the distal portion of your fibula. When a person injures an ankle either by spraining it or breaking it, there tends to be a lot of tenderness to the malleolus themselves and frequently, a lot of swelling over the top of them.

Question 22

What does the tarsal bones do

Answer 22

The tarsal bones articulate with the metatarsals which are the long bones that make up the mid foot and end up connecting with the phalanges. You heard me right exact same name for the bones of the toes as the bones of the fingers. We cut you some slack on these ones.
