Study Notes
- Both hyaline cartilage and blood are types of connective tissues.
- The horizontal/cross-section/transverse plane divides the body or organ into superior and inferior portions.
- Simple cuboidal epithelium consists of a single layer of cells as tall as they are wide and has a spherical nucleus.
- Merocrine glands use exocytosis to secrete their products and are the most common type of multicellular exocrine gland.
- Mesenchyme is embryonic tissue that gives rise to all connective tissues.
- The median/sagittal plane divides the body or an organ into right and left sides.
- The arm is proximal/superior to the hand.
- Fibrocartilage connective tissue is located within the intervertebral disks.
- Leukocytes are cells of the immune system and protect the body from infections.
- Chondroblasts, hematopoietic stem cells, osteoblasts, and fibroblasts are cellular descendants of mesenchyme.
- Simple cuboidal epithelium is found around the lumen in kidney tubules, ducts, and glands.
- Collagen and elastic fibers are clearly visible in areolar connective tissue.
- The hyoid bone is unique in that it does not articulate with any other bone.
- Protection is the function of stratified squamous epithelium.
- Vertebral arteries pass through the transverse foramen on cervical vertebrae.
- The head of the femur fits into the acetabulum on the hip bone.
- The thyrohyoid muscle inserts at the hyoid bone.
- The transverse abdominis muscle originates at the ribs and iliac crest.
- The zygomaticus elevates the corners of the mouth, originates at the zygomatic bones, and inserts at the corner of the mouth.
