Anat: Introduction to Limbs

Question 1

What is the median plane? Another name for it aswell

Answer 1

The midline, longitudinal plane dividing the head and torso into equal right and left halves

Also known as the middle sagittal plane

Question 2

What does superior and inferior mean?

Answer 2

Superior: Nearer to the head
Inferior: Nearer to the feet

Question 3

What does and anterior and posterior mean?

Answer 3

Anterior: nearer to the front

Posterior: Nearer to the back

Question 4

What does lateral and medial mean?

Answer 4

Lateral: Farther from median plane

Medial: Nearer to median plane

Question 5

What does proximal and distal mean?

Answer 5

Proximal: nearer trunk or point of origin

Distal: Farther from trunk or point of origin

Question 6

What are the palpable sections of the pelvis?

Answer 6

• Pubic tubercle
• ASIS (Anterior superior iliac spine
• Iliac crest
• PSIS (Posterior superior iliac spine)

Question 7

What is the most efficient standing position in relation to the pelvis?

Answer 7

When the pubic tubercle and the anterior superior iliac spine (ASIS) is in one vertical plane

Tilts away from the verticl plane can cause back pain as the spine will have to compensate for the tilt

Question 8

What part of the pelvis do we sit on?

Answer 8

Ischial tuberosity which is only covered by a small layer of tissue when seated. When standing it is covered by the gluteus maximus muscle

Question 9

What are the key parts of the femur?

Answer 9

Head - (ball that is joint to the hip

Greater trochanter - (other section at the top of the bone)

Lateral condyle - (front outside section of the bottom of the femur)

Medial condyle - (front inside section of the bottom of the femur)

lateral epicondyle - (rear outside section of the bottom of the femur)

medial epicondyle - (rear inside section of ht bottom of the femur)

Question 10

What are the main features of the tibia?

Answer 10

Medial condyle - (upper inside section of the top of the tibia

Lateral Condyle

Medial epicondyle

Tibial crest - (palpable section of bone known as the shin

Medial malleolus - Lower inside section of the tibia which connects to foot bones

Question 11

What are the main features of the fibula?

Answer 11

Doesn’t form a joint with femur

Fibular head - Top section of the bone on the opposite side of the tibia

Lateral malleolus - Bottom section of bone that is palpable on the outside of the leg by the ankle

Question 12

Where does the line of gravity go through the body?

Answer 12

Should go through the hip joint, patella and the middle of the foot

Question 13

Where is the only bone connection in the upper body?

Answer 13

Humerous linked to the clavicle

Question 14

What are the main features of the scapula?

Answer 14

Coracoid process - A short projection from the scapula, to which part of the biceps is attached

Acromion - extends laterally over the shoulder joint

Glenoid fossa - The humerus is held in place within the glenoid cavity by means of the long head of the biceps tendon.

Question 15

What are the main features of the humerus?

Answer 15

Head - Top section of the bone that is joined to the glenoid fossa in the scapula

Capitulum - It articulates with the cupshaped depression on the head of the radius

Trochlea -

Question 16

What are the main features of the radius?

Answer 16

Head - top of the bone where the radius attaches to the humerous

Styloid process - a slender projection of bone, such as that from the lower surface of the temporal bone

Question 17

What are the main features of the ulna?

Answer 17

Olecranon - hooks around the back of the humerus where the humerous joins to the ulna

Coronoid process - a projection from the front of the ulna forming part of the articulation of the elbow.

Styloid process - lower section of the ulna that joins to the hand bones
