Systems Of The Human Body -Skeletal- (lecture 3)

Question 1

Junction between two or more bones

Answer 1

Joints

Question 2

The 4 main types of joints

Answer 2

Synovial
Solid
Fibrous
Cartilaginous

Question 3

Fibrous Joints description

Answer 3

Bones united by fibrous tissue

Amount of movement dependent on the length of the fibres

Question 4

Cartilaginous Joints Description

Answer 4

Synchondrosis: Joints are united by hyaline cartilage
Form the epiphyseal plate; if anything happens to this plate, the bone will stop growing
Symphysis-joints united by fibrocartilage

Question 5

Surrounds the ends of bones

Answer 5

Joint capsule

Question 6

This membrane produces the synovial fluid that lubricates and nourishes the joint

Answer 6

Inner layer- Fibrous layer

Question 7

Completely surrounds joint

Blends with periosteum of bones

Usually thickened by ligaments

Answer 7

Outer layer-synovial membrane

Question 8

Types of synovial joints

Answer 8

Hinge Joints-bends

Pivot Joints-rotates

Saddle Joints-one on the other

Plane Joints-two flat surface

Ball and socket joints (has socket that joint fits into )- shoulder, hip

Question 9

Parallel collagen fibres - designed to withstand high tensile forces

Are one of the structures that help limit joint range of motion

Answer 9

Ligaments

Question 10

Ligaments Information

Answer 10

Can be either part of the joint capsule (intrascapular; within) or external to the joint capsule (extracapsular; outside)

Capsule and ligaments have nerve endings that enable pain to be sensed

Question 11

Tough connective tissue layers

Answer 11

Fascia

Question 12

Fascia Description

Answer 12

Enables movement between structures

Reduces friction

What you are working with when you foam role, get a massage

Provides support to structures

Transmits vessels and nerves from one area to another
