2025 Questions and Answers(verified

Nervous Tissue Characteristics - CORRECT ANSWER-Description: Neurons are branching cells cell
processes that might be quite long extend from the nucleus-containing cell body. Also contributing to
nervous tissue are non irritable supporting cells.
Function: Transmit electrical signals from sensory receptors and to effectors (muscles and glands) which
control their activity.
Location: Brain, spinal cord, and nerves
, Skeletal Muscle Tissue - CORRECT ANSWER-Description: long, cylindrical, multinucleate cells; obvious
striations
Function: voluntary movement; locomotion, manipulate of the environment; facial expression;
voluntary control
Location: in skeletal muscles, attached to bones or occasionally to the skin
Cardiac Muscle Tissue - CORRECT ANSWER-Description: branching, striated, generally uninucleate cells
that interdigetiate at specialized junctions
Function: as it contracts, it propels blood into the circulation; involuntary control
Location: walls of the heart
Smooth Muscle Tissue - CORRECT ANSWER-Description: Spindle-shaped cells with a central nuclei ; no
striations; cells arranged closely to form sheets
Function: propels substances or objects along internal passage ways; involuntary control
Location: mostly in walls of hollow organs
Explain the principle of complementarity. - CORRECT ANSWER-Anatomy and physiology are
inseparable because function always reflects structure examples.) bones support and protect body
organs because they contain hard mineral deposits and, blood flows in one direction through the heart
because the heart has valves that prevent back flow.
Levels of structural organization (in order of increasing complexity) - CORRECT ANSWER-1) Chemical
Level- At this level atoms, tiny building blocks of matter combine to form molecules such as water and
proteins.
2) Cellular Level- All cells have some common functions, but individual cells vary widely in size and
shape, reflecting their unique functions in the body.
3) Tissue Level- Tissues are groups of similar cells that have a common function
4) Organ Level- Organs are made up of different tissues.
5) Organ (System) level- Organ systems consist of different organs that work together closely.
6) Organismal Level- The human organism is made up of many organ systems.
11 Organ systems of the body (major functions) - CORRECT ANSWER-1) Integumentary System- Forms
the external body covering.
