Where is the hyoid bone located and in which skeletal division does it belong? What other bones belong in that division?
The hyoid bone is located in the neck.
The hyoid bone is a part of the axial skeletal division
The other bones in the axial skeletal division are vertebrae, rib cage, skull, and facial bones.
What are the three functions of bone?
Support and protect internal organs
Form attachments of muscles to facilitate movement
Mineral storage
Fat storage and hematopoiesis
What are the functions of cartilage?
Line the articular surface/facet of bones
Form entire structure
Hyaline Cartilage
Smooth and glassy appearance with large amounts of collagen
Found in articular surfaces of bones and in the larynx, trachea, and bronchi
Elastic Cartilage
Very flexible with less collagen and more elastic fibers than hyaline cartilage
Found in ear and ear canal, epiglottis, and nose
Fibrous Cartilage
Tougher than all other cartilages and made of dense collagenous fibers
Present in areas most subject to frequent stress (TMJ, vertebral discs)
List functions of glia cells
Myelination
Creating cerebrospinal fluid
Support/maintain chemical environments
Nutrient transport
Repair damaged axons
What is the difference between white and gray matter? Where do we find each?
Grey matter – in the CNS
Contains cell bodies, dendrites, unmyelinated axons, synapses, and glial cells of the neurons in the brain
Cerebral cortex
White matter – in the CNS
Contains myelinated axons and glial cells that produce myelin
White matter fibers
What cranial bone is shaped like a butterfly? What is the function of this bone?
The sphenoid bone is shaped like a butterfly and helps form the base of the cranium.
frontal lobe
executing and planning movements
parietal lobe
receive and interpret sensory information from the body
temporal lobe
receive and interpret auditory information
occipital lobe
receive and interpret visual information from retinas
