Flashcards in Anatomical Terminology Deck (27):
1

What is anatomical position? Position of limbs?

Supine (on your back) with arms supinate do and toes pointing forward.

2

Sagittal sections divide the body into?

Left and right

3

Frontal = coronal

Divides body into front and back

4

Transverse sections

Horizontal section

5

Superior and inferior

Rostral and caudal

6

Anterior and posterior

Ventral and Dorsal

7

In the middle vs off to the side

Medial vs. lateral

8

Extrinsic muscle

Has its insertion or maybe origin outside the region of interest

Intrinsic - both attachments occur in region of interest

9

Valgus

Deviation away from midline (l for lateral)

10

Varus

Deviation of distal bone towards the midline

11

Which plane does F/E occur in?

The Sagittal plane

12

Abduction vs adduction

ABduct away from midline

ADduct towards midline

13

Internal vs external rotation

Internal- ventral surface towards median

External - ventral surface away from median

14

Isometric contraction

Muscle contracts but no shortening of the muscle occurs

15

Concentric contraction

Contraction is occurring with shortening of the muscle

16

Eccentric contraction

Tension generated while muscle is lengthened.

17

Axial skeleton

Skull, spinal column, rib cage

18

Appendicular skeleton

Shoulder girdle and long bones of the arm/ Pelvic girdle and long bones of the leg

19

Fibrous Joints

least mobile of the 3 classifications
Includes: suture (skull bones), syndesmosis (radius/ulna or tibia/fibula) and gomphosis (tooth socket)

20

Cartilaginous = Fibrocartilaginous Joints

Synchondrosis = growth plate
Symphysis - cartilage remaining in the adult skeleton (i.e intervertebral discs and the pubic symphysis)

21

Synovial Joints

Most mobile of the 3 classifications

22

Synovial Joints typically include which structure?

A fibrous joint capsule with internal synovial membrane that produces synovial fluid for lubrication of the articulating surfaces covered in hyaline cartilage

23

Example of a Plane Joint

Found in intercarpal joints of hand

24

Uniaxial synovial joints include which types (2)?

Hinge - elbow, knee
Pivot - radius, ulna and humerus

25

Biaxial synovial joints include which types (2)?

Condyloid - carpometacarpal joints of hand
Saddle - carpometacarpal of thumb

26

Triaxial joints example?

Ball and Socket - think femur in pelvis or humerus in scapula

27

Hilton's Law states....?

nerves that supply a joint also supply the muscles moving the joint AND skin overlying the joint
