Study Notes
Epithelial Tissue
- Epithelial tissue is characterized by having both an apical (top) and a basal (bottom) surface.
- It is avascular, meaning it lacks blood vessels.
- Epithelia are classified into two major types based on cell layering: simple and stratified.
- Classification is further categorized by the number of cell layers and their general shape.
Types of Epithelial Tissue
- Simple columnar epithelium consists of a single layer of tall cells (columnar).
- Stratified squamous epithelium contains multiple layers of cells, often flat (squamous).
- Pseudostratified ciliated columnar epithelium appears to be stratified but is actually a single layer with varying cell heights.
- Simple cuboidal epithelium comprises a single layer of cube-shaped cells.
Connective Tissue
- Connective tissue provides structural support and energy storage to other tissues.
- It typically contains a large amount of extracellular matrix.
- The matrix is composed of ground substance and protein fibers: collagen, reticular, and elastic fibers.
Muscle Tissue
- Muscle tissue consists of specialized cells for contraction.
- Three types of muscle tissue exist: skeletal (voluntary, striated), cardiac (involuntary, striated, with intercalated discs), and smooth (involuntary, non-striated).
- Skeletal muscle allows for voluntary movements, while smooth muscle helps move substances through hollow organs.
Neural Tissue
- Neural tissue transmits information across the body, relying on neurons and neuroglia.
- Neurons carry electrical impulses, composed of a cell body and axon.
- Neuroglia provides support and protection for neurons but do not conduct electrical signals.
Facial Muscles
- The frontal belly of the occipitofrontalis muscles protract the scalp, while the platysma depresses the jaw.
- Important facial muscles include the orbicularis oculi (closes the eye), zygomaticus major (raises the corners of the mouth when smiling), and buccinator (tenses the cheeks).
- Muscles visible on the body surface are often classified as superficialis.
Eye Muscles
- Extrinsic eye muscles control eye movement; for example, the superior rectus allows upward gaze while the inferior rectus allows downward gaze.
- The medial rectus muscle can be surgically adjusted to correct strabismus (crossed eyes).
Jaw and Cervical Muscles
- The masseter is the strongest muscle responsible for elevating the mandible during mastication.
- Auxiliary muscles such as temporalis assist in the movement and positioning of the jaw.
Muscle Characteristics
- Muscles with fibers running parallel to the body's long axis are described as rectus.
- Muscles with oblique fibers run at angles to the long axis.
- Names often incorporate terms that indicate location, such as "capitis" for muscles attached to the head, or "-glossus" for those associated with the tongue.
Summary of Important Terms
- Lacunae: spaces in bone where osteocytes reside.
- Chondrocytes: cells found in cartilage, within lacunae.
- Striations: visible in skeletal and cardiac muscle fibers, indicating their organized structure.
These notes provide a condensed overview of the key characteristics and functions of different tissue types, combined with specific muscle functions and classifications.
