Q

What is the function of the skeletal system?

A

The main function of the Axial Skeleton (composed by the skull, spine and ribcage)is to protect the internal organs and support the Appendicular Skeleton(composed by the limbs, arms and legs plus the clavicle and pelvis, its main function is movement and support

Q

Where would you find bone marrow and what is its function?

A

It is found in the bones. There are two types of bone marrow. Red bone marrow (found at the the end of long bones), in flat bones in the cancellous (“spongy”) part of the bone).

17
Q

Name the bones of the hand

A

8 carpals
5 metacarpals
14 phalanges

18
Q

Name 3 bones of the pelvic girdle

A

Ilium,
Ischium
Pubis

19
Q

Name the categories of joints

A

Synovial
Cartilaginous
Fibrous

20
Q

Types of muscle

A

Smooth
Cardiac
Voluntary
Skeletal

21
Q

List 4 bones

A

Femur
Ulna
Tibia
Humerus
Radius

22
Q

Name the 4 basic types of tissue.

A

Nerve, Epithelial, Connective, Muscle

23
Q

Name 4 functions of muscles.

A

Provide strength, Balance, Posture, Movement, Heat for the
body to keep warm, Cardiac contractility

24
Q

What is the difference between voluntary and involuntary muscles?

A

Involuntary muscles are
muscles controlled only by the autonomic nervous system (digesting food, peristalsis) .
These cannot be controlled consciously. While Voluntary muscles we can control them
(walking, smiling)

25
Q

Where does the muscle take the energy from when it needs it?

A

The process of muscle
contraction requires chemical reactions at cellular level + electrical messages from the
nervous system. When a cell needs energy for chemical reactions, ATP (adenosine
triphosphate) is broken down to find this energy.

26
Q

Name three diseases and disorders of the muscular system

A

Fibromyalgia, Atony Atrophy. cramps , Ms

27
Q

What are the functions of - a) a muscle? - b) a tendon? - c) a ligament?

A

Tendons and ligaments are connective tissues that transmit mechanical forces between muscles and bones. Tendons attach muscle to skeleton, whereas ligaments attach bone to bone and stabilize skeletal joints. Muscles function is movement and to produce force and motion

28
Q

38) Where are the sacro-iliac joints located in the body?

A

The sacroiliac joint is the joint between the sacrum and the ilium bones of the pelvis

29
Q

The main three functions of the skeletal system

A

Support of the body, Locomotion, provide protection for internal organs, produces of blood cells + the storage of minerals, particularly calcium, + development

30
Q

Name the 4 components of the Skeletal System

A

The skeletal system is composed of four main fibrous and mineralized connective tissues: bones, ligaments, tendons, and joints.

31
Q

42) What does the Appendicular skeleton consist of?

A

The Appendicular Skeleton consists of 126 bones that include both the upper and lower limbs and bones shoulders girdle and pelvic girdle

32
Q

How many bones are in the foot?

A

And in the hand? 26 bones in the foot, 27 bones in the hand

33
Q

What is bone marrow? Name one function and where in the body would you find it?

A

Bone marrow is soft, flexible connective tissue within bone cavities, bone marrow functions primarily to produce blood cells and to store fat. Red V Yellow Marrow. In adults, red marrow is mostly in the skull, pelvis, spine, ribs, sternum, shoulder blades, and near the point of attachment of the long bones of the arms and legs. The red marrow produces blood cells. Yellow marrow consists primarily of fat cells. Yellow marrow is found in spongy bones and in the shaft of long bones. When blood supply is extremely low, yellow marrow can be converted to red marrow in order to produce more blood cells.

34
Q

How many different types of bones are in the human skeleton?

A

There are five types of bones in the human skeletal system: Long, Short, Flat, Irregular, Sesamoid.

35
Q

Name the 3 different types of joints.

A

Fixed or Fibrous joint, cartilaginous or slightly movable joint, freely movable or synovial joint.
