Anatomy and Physiology of the Muscles Flashcards
supports the body with strong bones, cartilage and ligaments
Skeletal System
muscle to bone, contraction and pulling of tendons
Body Movement
has minerals, adipose tissue
Mineral Storage
matrix that always contains, collagen, ground substances, and other organic molecules
Extracellular Matrix
bone forming cells, does the repairing and modeling of bones
Osteoblasts
osteoblasts that become surrounded by matrix
Osteocytes
bone destroying cells, bone absorption and also contribute to the bone repair modeling
Osteoclasts
where can you mostly find long bones in the human body?
upper and lower limbs
where can you mostly find short bones in the human body?
wrist and ankle
where can you mostly find flat bones in the human body?
skull, ribs, scapula and sternum
where can you mostly find irregular bones in the human body?
vertebrae and facial bones
bones that are porous, has less bone matrix and more space than compact bone
Spongy bones
bones that are less porous and has less space than spongy bones
Compact bones
shaft of the bone
Diaphysis
Proximal and Distal end of the bones
Epiphysis
covers the ends of the epiphyses where the bone articulates with other bones and it is also made up of hyaline cartilage
Articular Cartilage
canal inside the shaft
Medullary Cavity
covers the outer surface of bone except where an articular cartilage is present
Periosteum
lines and inner cavities of the bone
Endosteum
composed of cartilage, between each epiphysis and the diaphysis
Epiphyseal plate/ growth plate
soft tissue that fills the spaces of diaphysis and epiphysis
Bone marrow
marrow that has adipose tissue
yellow marrow
marrow that produces blood cells
red marrow
osteoblasts deposit new bone matrix on the surface of bones
Appositional Growth
the removal of existing or old bone by osteoclasts and the deposition of new bone by osteoblasts
Bone remodeling
calcium absorption
Vitamin D
increases collagen formation
Vitamin C
increases general tissue growth
growth hormone
required for normal growth of all tissues
Thyroid hormone
when there’s low calcium what happens to the osteoclastic
increases its activity
when there’s high calcium what happens to the osteoclastic
decreases its activity
type of muscle responsible for facial expressions
face muscles
raises the eyebrows
occipitofrontalis
closes the eyelids, wrinkles at the lateral corners of the eye
orbicularis oculi
raises the upper eyelids
levator palpebrae superiors
draws the eyebrows inferior and medially
corrugator supercili
