SLHS 3400 Exam 1 (Anatomical terminology, tissue types,
cranial nerves, muscle cell anatomy and physiology)
Questions With Complete Solutions
regularly arranged dense CT
- adapted for tension in 1 direction
- fibers have an orderly parallel appearance
- most frequently composed of collagen
- silverly white and tough, yet somewhat pliable
- ex: tendons and ligaments
irregularly arranged dense CT
- adapted for tensions occurring in varied directions
- no consistent orientation of fiber bundles
- ex: deep skin layers and around the heart
specific types of dense connective tissue
tendons, ligaments, fascia, reticular, aponeuroses
tendons
- tough, non-elastic cords that connect muscle to bone or
cartilage
- ex: the Achilles tendon connects muscle to bone
ligaments
- elastic bands of tissue that connect bone to bone, bone to
cartilage, and cartilage to cartilage
- ex: sphenomandibular ligament
,fascia
- membranous sheets that organize muscle fibers into functional
units
- ex: temporal fascia covers the temporalis muscle, this muscle
helps with chewing
reticular
- a delicate matrix of cells which has processes that extend in all
directions to join the processes of neighboring cells
- ex: reticular tissue
aponeuroses
- tendinous sheets that cover muscle and can connect muscles to
the structures they move
- they move when the muscle contracts
- ex: the aponeurosis of the abdominal external oblique muscle
is a thin, strong membrane that covers the whole front of the
abdomen
cartilage dense CT
- rigid connective tissue capable of growth and able to withstand
large forces of compression, yet they may tear easily
- it is not as rigid as bone
- our bodies first form with all cartilage, but as we grow the
cartilage ossifies into bones
- 3 types of cartilage: hyaline, fibrous, elastic
hyaline cartilage
, - most rigid type
- covers articular surfaces of joints, providing a smooth surface
for mocements
- we find hyaline cartilage in the nose, ends of long bones,
trachea, and bronchial tubes, all of the cartilage of the larynx is
hyaline except the epiglottis
- hyaline cartilage occurs around the tracheal ring, as illustrated
by number 4
fibrous cartilage
- made mostly of collagen and provides support and fusion
- we find it in the intervertebral discs btw the cartilage pads of
the knee
- dark spots in this fibrous cartilage are the nuclei of the
chondrocytes
elastic cartilage
- contains a high amount of elastin and is yellow in color
- provides support and shape; however, is more pliable and
ossifies to a lesser degree than hyaline cartilage
- a threadlike network of lines in this image are the elastic fibers
- ex: epiglottis, external ear, and Eustachian tubes
bone
- rigid matric composed of bone cells, collagen fibers, and
ground substance
- collagen makes the bones strong, while the inorganic minerals
salts make the bone hard
- 2 types of bone that interdigitate with each other along the
cranial nerves, muscle cell anatomy and physiology)
