How many adult skeleton contains how many total bones
206
How many bones are contained in the axial skeleton
80
List the 5 main parts to the axial skeleton and the bones and how many of each they contain
- Skull: 24 (cranium 8) (face 16)
- Hyoid: 1
- ossicles: 6
- thorax: 24 ribs 1 sternum
- vertebra: 26 bones
Cranial bones
- frontal
- parietal
- temporal
- occipital
- sphenoid
- ethmoid
How many total bones make up the appendicular skeleton
126 bones
What are the functions of the pectoral girdle
supports the upper limb, allows movement of upper limbs, points of muscle attachments
What bones make up the pectoral girdle
clavicle and scapula
Frontal
- 1 bone
- forehead, top of eye orbits, most of anterior skull
Humerous
2 bones- attaches to scapula at proximal ends and ulna and radius distally
ulna
2 bones, medial side of the body
parietal
- 2 bones
- most of the side of your head
radius
2 bones, lateral side of the body
temporal
- 2 bones
- inferior side of cranium
carpals
16 bones, at the wrist
occipital
- 1 bone
- forms base of skull
metacarpals
5 bones, palm of hand
sphenoid
- 1 bone
- join all other bones
phalanges
28 bones, the fingers
ethmoid
- 1 bone
- major supporting structure of nasal cavity
What two bones make up the elbow
humerous and ulna
functions of the pelvic girdle
provides a strong stable support for vertebral column, protect pelvic visceral organs, attaches lower limbs to axial skeleton
Coxal bones
3 separate bones fused together by age 23
ilium
the flat and longest part of coxal bone
Ischium
lower posterior part of the bone
Pubis
anterior and interior part of the hip bone
obturator foramen
hole in between pubis and ischium
difference between male and female pelvic girdle
male- heavy and thick, narrow with less space in pelvic inlet and outlet, acetabulum is larger and faces more laterally, obturator foramen is round, the pubic arch is less than 90 degrees
female- the pelvic area is thinner and lighter, wider with more space in the pelvic inlet and outlet, acetabulum is small and faces less laterally, obturator foramen is oval and the pubic arch is greater than 90 degrees
What is broken when a person is considered to have a “broken hip”
head of femur
What bones make up the lower limbs
30 bones on each side
femur (2)
patella (2)
Tibia (2)
fibula (2)
tarsals (14)
metatarsals (10)
phalanges (10)
Define endocrine
internal secretion
functions of hormones
maintain homeostasis, regulates activity of smooth and cardiac muscle, regulate metabolic process, controls growth and development, influences reproductive process, participates in circadian rhythms
steroid hormones
lipid soluble
ex) all sex hormones
