Anatomical terms
The bone proximal to the ulna and radius.
What is the humerus?
The two bones that make up the shoulder girdle
What is the scapula and clavicle?
An articulation
What is a joint?
A muscle's ability to shorten
What is contractility?
The thick myofilament responsible for sliding the thin myofilament closer towards the M line during muscle contraction.
What is myosin?
The bone lateral to the tibia
What is the fibula?
The name for ribs #11 and #12
What are floating ribs?
Joint type that does not allow movement and does not have a joint cavity.
An example of this joint type is found within the human skull.
What is a fibrous joint?
A type of muscle that is involuntary, non-striated with uninucleated muscle fibers.
What is smooth muscle?
A bundle of muscle fibers.
What is a fascicle?
The movement involved at the shoulder when contracting the pectoralis major during a seated rows.
What is abduction?
The 3 bones that make up the pelvic girdle
What is the ilium, sacrum and pubis?
A small fluid-filled sacs found in areas of high stress.
What is a bursa?
1. Skeletal muscles contract exerting forces on the tendons.
2. Generating body heat by shivering
3. Postural muscles stabilize and maintain body positions
4. Movement of substances within the body
What are the 4 functions of muscles?
What is myelin sheath?
The name of a foot position where the toes are pointed upward.
A bone type that has curved surfaces and vary from being quite thick to very thin.
These bones provide protection and the broad surfaces also provide a large area for muscle attachment
What is a flat bone?
A type of synovial joint that features two flat surfaces that slide over one another.
They allow a tiny amount of movement in all directions.
Example: Between tarsals in the ankle.
What is a gliding joint?
The increase in number of myofibrils and thus, muscle mass
What is hypertrophy?
The neurotransmitter responsible for increasing the permeability of the post-synaptic membrane of a neuromuscular junction.
What is acetylcholine (Ach)?
The position of one's arm spread out away from the midline.
What is abduction?
The tubular shaft that runs between the proximal and distal ends of a long bone.
What is a diaphysis?
The smooth, white tissue that covers the ends of bones where they come together to form joints.
What is articular cartilage?
The muscle that allows for dorsiflexion and plantar flexion movement.
What is the anterior tibialis?
The structure that forms when a myosin head attaches to an actin myofilament.
What is a cross-bridge?
