    What is the function of epithelial tissue?

    Covers surfaces and secretes substances.

    What distinguishes connective tissue from other tissues?

    It supports and binds other tissues.

    What are the types of muscle tissue?

    Smooth, striated skeletal, and striated cardiac.

    What is the role of nervous tissue?

    Transmits signals throughout the body.

    How do organs differ from systems?

    Organs consist of multiple tissues; systems consist of multiple organs.

    What defines a hollow organ?

    It has a central lumen and layered walls.

    What is the structure of a parenchymatous organ?

    It lacks a lumen and is made of dense cells.

    What are the three main body portions?

    Head, trunk, and upper/lower limbs.

    What is the sagittal plane?

    Divides the body into right and left halves.

    What does the frontal plane separate?

    Divides the body into anterior and posterior sections.

    What is the transverse plane?

    Divides the body into superior and inferior parts.

    What does proximal mean?

    Closer to the origin of a structure.

    What is the difference between flexion and extension?

    Flexion decreases angle; extension increases it.

    What are the main functions of the skeletal system?

    Supports body, stores minerals, and produces blood cells.

    What characterizes long bones?

    Length exceeds width; includes a diaphysis and epiphyses.

    What are flat bones?

    Bones where width and length are greater than thickness.

    What defines short bones?

    Bones with equal dimensions in all directions.

    What are synarthroses?

    Immovable joints connected by connective tissue.

    What are diarthroses?

    Freely movable joints with a synovial cavity.

    What is an example of a hinge joint?

    Elbow joint allowing flexion and extension.

    What is the role of the rotator cuff muscles?

    Stabilize the shoulder joint and prevent dislocation.

    What is the structure of the scapula?

    A flat, triangular bone with multiple surfaces and processes.

    What is the significance of the glenoid cavity?

    It articulates with the head of the humerus.

    What is the function of the clavicle?

    Connects the arm to the body and stabilizes the shoulder.

    What distinguishes cervical vertebrae?

    They have transverse foramina for vertebral arteries.

    What is unique about lumbar vertebrae?

    They have larger bodies to support more weight.

    What is the sacrum composed of?

    Fused sacral vertebrae forming a triangular bone.

    What is the role of the pelvic girdle?

    Supports the weight of the upper body and connects to the legs.
