Phenotype: extraocular musculature lacks parts or has fewer parts of type dorsal rectus, abnormal
Note: This statement combines anatomy and/or ontology terms with phenotype quality terms to create a complete phenotype (EQ) statement. For detailed information on individual terms, click the hyperlinked term name.
Name: extraocular musculature
Synonyms: ocular musculature
Definition: Muscle system surrounding the eye. The extraocular musculature is derived from the neural crest. The extraocular muscles assume their adult configuration between 66 and 72 hpf. They differentiate contemporaneously with the eye vesicle, form precise anatomic attachments to sclera and bone, and are innervated by cranial nerves 3, 4, and 6.

Name: lacks parts or has fewer parts of type
Synonyms: loss of
Definition: The bearer of this quality has_part < n of the indicated entity type, where n is the normal amount for a comparable organism. Note that the bearer of the quality is the whole, not the part. Formally: If a bearer entity e has fewer parts of type X at time t, then the number of instances x of X at t such that x part_of e is < n, where n is either the normal number for comparable entities, or n is stated explicitly. This case includes the limit case, where the bearer lacks all parts of the specified type.

Name: dorsal rectus
Synonyms: dorsal recti, superior rectus
Definition: Extraocular muscle that inserts at the scleral corneal junction on the dorsal side of the eye. The dorsal rectus is innervated by the oculomotor nerve. The dorsal rectus and dorsal oblique muscles have overlapping insertions in the adult eye though they have distinct insertion sites in 5dpf fish.
