Which process of the mandible articulates with the temporal bone

Condylar Process (Mandibular Condyle)

Where is the hyoid bone located

In the anterior neck, between the mandible and larynx

What are the functions of the vertebral column

Supports the head and trunk
Protects the spinal cord
allows movement
Maintains posture
Transmits body weight to the pelvis

what stcture does the vertebral column protect?

Spinal cord

How many cervical, thoracic, and lumbar vertebrae are there

C: 7
T:12
L:5
S: 5

how many pairs of ribs are in the human body

12 pairs ( 24 ribs)

How many true, false, and floating ribs are there.

1- 7: 7 pairs — True ribs (attach directly to the sternum by their own costal cartilage)
8-12: 5 pairs— False ribs (8–10 attach indirectly)
10- 12: 2 pairs — Floating ribs (no sternal attachment)

which bones belong to the appendicular skeleton

“Please use proper legs”
Pectoral girdle, upper limbs, pelvic girdle, and lower limbs

what bones from the pectoral girdle

Clavicle and scapula

which bones articulate with the humerus

Scapula, radius, ulna

What are the characteristics of the male pelvis?

narrower and deeper pelvis
haiver bone
smaller pelvic inlet
narrow subpubic angle
less flared iliac bones compared to female

what acts as a fulcrum for a long bone during movement

a Joint

what is a diarthrosis

a freely movable joint

What are the characteristics and types of fibrous joints

Bones are connected by dense fibrous connective tissue, without a joint cavity.
Types include sutures, synesmoses, and gomphoses

what type of joint is a skull suture

fibrous joint; functionally classified as a synarthrosis (Immovable)

where is articular cartilage found

covering the ends of the bone in synovial joints, reducing friction and absorbing shock

how is the pubc symphysis classified

Cartilaginous joint ( Symphysis); Functionally an amphiarthrosis (slightly movable)

what are the characterics and types of cartulagious joints

Bones connected by cartilage, without a joint cavity
Synchondrosis: Hyaline cartilage
Symphysis: Fibrocartilage
