body to keep warm, Cardiac contractility

Question 24

What is the difference between voluntary and involuntary muscles?

Answer 24

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)

Question 25

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

Answer 25

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.

Question 27

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

Answer 27

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

Question 28

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

Answer 28

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

Question 29

The main three functions of the skeletal system

Answer 29

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

Question 30

Name the 4 components of the Skeletal System

Answer 30

Question 33

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

Answer 33

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.
