(56 cards)
Cranial bones and facial bones
parietal bone, sutural bone, occipital bone, temporal bone, frontal bone, sphenoid bone, ethmoid bone
plus facial bones
Nasal, lacrimal, maxilla, zygomatic, vomer, mandible
Bones that make up the orbital socket
Sphenoid.
Frontal.
Zygomatic.
Ethmoid.
Lacrimal.
Maxilla.
Palatine.
male skull
more square chin, arch on eye, more of a 90 degree on, mandibular angle
female skull
More triangular chin, no Arch over eye, more round frontal bone, more than 90° angle on angle of mandible
Parts of vertebrae
7 cervical(neck) 12 thoracic(chest) 5 lumbar(lower back)
Difference between Atlas and axis
Atlas: right under head, makes a joint
Axis: the 2nd bone
Fits together with the superior articular faucet
True ribs
1-7
Directly connected to the sternum with hyaline cartilage
false ribs
8-12
not Directly connected to the sternum with hyaline cartilage
what joints the ribs to the sternum
hyaline cartilage
where do ribs articulate with the vertebra
with the thoracic vertabrea
floating ribs
11-12
do not articulate with the sternum
bones of the pectoral girdle
clavicle and scapula
bones of the upper limbs
Humorous, radius and unla, the 8 carpal bones in the wrist, 5 metacarpals in Palm, 14 phalanges in fingers
Major processes of upper limbs
Neck, greater tubercle, deltoid tuberosity(connects to deloitd), condyles, spine
Bones of the pelvic girdle and lower limbs
sacrum the coccyx and hip bones(ilium)
Humerus patella fibula fibula tarsals calcaneus phalanges
sex diffreces in pelvis
Male: more squared
Female: more round
all the S words and what they do.
Synovial: holds fluid,
suture: Stitches the skull,
Symphysis: fibrocartilage it is in the pubis and intervertebral disc,
Synarthrosis: Boars together no movement,
synchondrosis: Chondrocytes,
syndesmosis: 2 bones
Types of synovial joints
Plane joints; on the axial side to side movement wrist at radial / ulnar carpal joint
Hinge joint unaxial like hinge of a door elbow
Pivot joints unaxial one bone rotates on its longitudinal axis Atlas axis of vertebrae
condylar joints by axial oval concave surface of one bone convex of other metacarpal phalange joint
Saddle joints biaxial joint surface resemble saddle shape thumb carpal metacarpal joint
Ball and socket joints multi axial spherical head into cuplike socket hip and shoulder
Extra features of the knee joint
Meniscus cruciate ligaments collateral ligaments
What is a burse
sacs outside most synovial joints where ligaments muscles tendons or bones rub contain synovial fluid
all movements
Gliding mono axial Sternal clavicial joint, acromial clavicle joints, vertebrate costal joints
Angular motion flexion extension abduction adduction
Rotational motion pronate supinate
Parts of the muscles and the muscle cell
sarcolemma: plasma membrane
Sarcoplasm :cytoplasm
Sarcoplasmic: reticulum smooth ER stores calcium ++
Sarcomere: The Contracting unit of the muscle fiber each myofibril has a string of sarcomere which it shortened to cause contraction in the muscle
Membranes around the muscle bundle fascicle and cell
perimysium(fascicle), epimysium(muscle), endomysium(muscle fiber and cell)
