Intro to A&P
This is the smallest unit of life.
What is a cell?
The type of bone cell that breaks down bone tissue.
What is an osteoclast?
The main muscle of breathing.
What is the diaphragm?
The basic structural and functional unit of the nervous system.
What is a neuron?
The bone landmark called the olecranon is found on this bone.
What is the ulna?
The superficial medial hamstring
What is semi tendinosis
What direction do the palms face in anatomical position
What is an Anteriorly
The bone that forms the forehead.
What is the frontal bone?
This quadriceps muscle also crosses the hip joint.
What is the rectus femoris?
What is the tiny space where a message passes from one neuron to another?
What is a synapse?
This dense irregular connective tissue layer anchors the skin to underlying structures.
What is the deep fascia (or hypodermis)?
This powerful forearm extensor originates from the lateral supracondylar ridge and inserts on the base of the 2nd metacarpal.
What is the extensor carpi radialis longus?
What structure is made up of two or more tissues
What is an organ
This is the joint found between C1 and C2
What is atlanto-axial
The “rotator cuff” includes this muscle that initiates abduction.
What is the supraspinatus?
This type of neuron carries the signal from the spinal cord to a muscle, causing it to contract.
What is a motor neuron?
This type of cartilage covers the ends of long bones and reduces friction in joints.
What is articular cartilage (hyaline cartilage)?
This is the synergist to triceps brachii
What is anconeus
The cavity that contains the lungs and heart.
What is the thoracic cavity?
This bone forms the posterior part of the hard palate.
What is the palatine bone?
This deep arm flexor lies beneath the biceps brachii.
What is the brachialis?
This part of the brain controls balance and coordination.
What is the cerebellum?
The fluid is found within cells
What is intracellular fluid
The origin for rhomboids minor
What is spinous processes of C7 to T1
What structures are considered undifferentiated
What is a stem cell
These two bony landmarks articulate to form the atlanto-occipital joint.
What are the occipital condyles and the atlas (C1)?
This is the name of the connective tissue layer that surrounds a fascicle.
What is the perimysium?
Once acetylcholine binds to receptors on the muscle fiber’s surface, this structure carries the signal deep into the muscle to begin contraction.
What are T-tubules?
The part of a long bone that contains red marrow in children.
What is the epiphysis?
The origin for vastus lateralis
What is the lateral lip of linea Aspera
This serous membrane lines the walls of the abdominal cavity and also covers the surface of the abdominal organs
What is the peritoneum
This type of ossification forms most flat bones of the skull.
What is intramembranous ossification?
What rotator cuff muscle medially rotates the humerus
What is subscapularis
In order for acetylcholine to be released from the axon terminal into the synaptic cleft, this ion must enter the neuron and trigger neurotransmitter vesicle release, setting off the muscle contraction process.
What is calcium?
This anatomical structure stores calcium and releases it during muscle contraction.
What is the sarcoplasmic reticulum?
What do you call the ligament on the medial side of the knee
Tibial collateral
This necessary life function refers to all chemical reactions in the body, including those that build up and break down molecules.
What is metabolism?
This bone in the axial skeleton does not articulate with any other bone and serves as an attachment site for tongue and neck muscles.
What is the hyoid bone?
A client complains of deep, burning discomfort between the medial border of the scapula and the spine, worsened by prolonged computer work. You observe that the scapula on the affected side is slightly abducted and laterally rotated. Which scapular stabilizing muscle is most likely weak or inhibited, allowing this postural imbalance?
What are the rhomboids?
This division of the nervous system includes all the nerves that branch off the brain and spinal cord and is responsible for carrying sensory input to the CNS and motor commands back to the body.
What is the peripheral nervous system?
This flat bone is the only one in the body that forms entirely within a tendon and does not articulate directly with any other bones, yet plays a crucial role in movement efficiency and joint protection.
What is the patella?
This muscle, located deep to the biceps brachii, originates on the distal half of the anterior humerus and inserts on the ulnar tuberosity. Unlike the biceps, it does not cross the shoulder joint and is a powerful elbow flexor regardless of forearm position.
What is the brachialis?
