Lectures 1-7 Flashcards
Which tissues would you find in your knee joint?
Connective tissue (including cartilage and bone), muscle tissue, and nervous tissue.
What are the functions of nervous tissue?
Conducts electrical impulses and carries information.
What is the correct anatomical position?
Upright, facing forwards, feet together, palms facing forwards.
What is feedback in homeostasis?
When a controlled variable moves too far from the set point and the body responds to bring it back to normal.
What body parts are included in the lower limb?
Thigh, leg, and foot.
Which tissue is the least common in the body?
Nervous tissue (2%).
Which tissue includes blood and lymph?
Connective tissue.
What is the primary site of ion loss?
The kidney.
What is DFCT, and what are its characteristics?
Dense Fibrous Connective Tissue; contains fibroblasts, collagen, and some elastin, resists tension, and has little vascularity.
Where is the primary ossification center located, and what does it do?
In the diaphysis (shaft); it develops bone at different times.
What is homeostasis?
It supports normal function of body systems by maintaining conditions in the internal environment through regulatory mechanisms.
What does the axial skeleton consist of and what is its function?
Consists of the skull, vertebral column, and rib cage; it protects vital organs.
What body parts are included in the upper limb?
Arm, forearm, and hand.
What is the role of Osteoblasts?
They produce new bone matrix.
What are movements in the coronal plane?
Abduction and adduction.
What is required to maintain bone homeostasis?
Adequate dietary calcium and moderate exercise.
What is eversion?
Turning the sole of the foot away from the midline.
Describe the structure of limb bones.
Each limb has a single proximal long bone (humerus/femur), two distal long bones (ulna and radius/tibia and fibula), and bones of the hands and feet.
What does the term “medial” mean in anatomical terminology?
Closer to the midline of the body.
Describe the structure and function of the skull.
Made up of the cranium and facial bones; protects the brain and supports sensory organs.
What is an electrical gradient?
Uneven distribution of charges across a membrane.
Describe the functions of the skeletal system.
Support, movement, protection, storage of minerals, and red blood cell formation.
How does bone maintain homeostasis?
By balancing Osteoblast and Osteoclast activity to regulate bone formation and destruction.
What is the transverse plane?
The plane that divides the body into top and bottom sections.
